Enclosure, box or cabinet: Whatever you want to call them, where you install your speaker or subwoofer is critically important to their resulting performance. In this article, we focus on the simplest and most forgiving of enclosures to design and construct – the acoustic suspension or sealed enclosure.

The Laws of Physics

There are a few characteristics to keep in mind about every speaker. The first is that as frequency decreases, cone excursion increases. In fact, to produce the same acoustic output, a speaker must move four times as far for every halving of frequency. As an example, if your subwoofer were moving 1 mm at 80 Hz, it would have to move 4 mm to produce the same output at 40 Hz. To produce the same output at 20 Hz, it would have to move 16 mm.

A speaker includes an element called a spider. The spider stores energy when the voice coil of a speaker moves the cone forward or rearward from its resting position. When the cone reaches the end of its travel and comes to a stop, the stored potential energy in the spider wants to be released. This stored energy pulls the cone in the opposite direction. Each transfer of energy includes some losses, and eventually, the cone comes to rest.

Think of the cone motion like a swing at the park. You exert a force on the swing to get it started, and it continues to swing back and forth with a decreasing amplitude until it comes to a stop. Thankfully, a speaker stops moving a lot faster than the swing at the park.

In a speaker, this transfer of energy from the cone to the spider and back is most efficient at a specific frequency. We call this the resonant frequency of the speaker. At the resonant frequency, there is a dramatic increase in impedance because the spider stores a great deal of energy. This energy storage causes the cone to want to continue to move. The movement of the voice coil moving through the magnetic field generates a voltage. This voltage generates a flow of current in the opposite direction to the current flowing from the amp. We represent this opposition to current flow as an increase in impedance.

We also have to consider that every speaker is limited in how far the cone can move. Once we exceed the excursion limitations of the speaker, bad things happen. The voice coil former can hit the back plate. The suspension components may be compromised and start to fail. As a by-product of the cone, dust cap, surround, spider and motor geometry, harmonic distortion also increases as excursion increases.

Our goal in designing any audio system should be to keep distortion as low as possible. Most of the distortion at low frequencies is resonance. These resonances decrease as we move above the resonant frequency of the speaker. The spider and the changing motor force, as the coil moves past the edge of the gap, are the biggest contributors to distortion.

Why Do We Need an Enclosure?

Let’s consider a few additional characteristics. The low-frequency roll-off of a speaker is a high-pass filter. The spider in the speaker is like a capacitor—a spring stores energy and so does a capacitor. The air inside the box is also a spring, and it is in parallel with the spider. The air spring and the spider work together at the same time to do the same thing. The combination of the air spring and the spider increases the high-pass filter frequency. Yes: Contrary to our efforts to produce as much low-frequency information as possible, an enclosure limits low-frequency reproduction.

If that is the case, why do we want to limit cone motion? Consider what we’ve said about how much excursion is required to reproduce low frequencies and about distortion. Limiting low-frequency output from our speaker is not an ideal goal, but limiting some of the really low frequencies to get the right amount of bass at higher frequencies is worthwhile.

There is a benefit to increasing the resonant frequency of the speaker and enclosure system. Let us say we have a subwoofer with a Q of 0.5 and it is our goal to have a total system Q of 0.707. We choose an enclosure air volume that increases the Q, which then increases the system output at the new resonant frequency. Yes, we sacrifice output at lower frequencies, but we gain output around the new system resonant frequency.

I Want More Bass!

Modern speaker designs continue to reduce distortion through computer simulation and modeling of material behavior. Qualified and properly equipped speaker designers can simulate spider, cone and surround behavior to analyze individual resonance and distortion behaviors. They also can model the interaction between the voice coil and the motor structure to predict changes in magnetic field strength and inductance that can further affect how a speaker will sound at moderate to high excursion levels.

These advancements have resulted in speakers that produce less distortion at higher excursion levels. This improvement in performance allows enclosure designers to build speaker systems that will play lower and louder.

Some basic principles govern low-frequency sound reproduction. Cone area is critical. An old article published by the Audio Engineering Society called “The Problem with Low-Frequency Reproduction,” by Saul J. White, included a graph that compared cone excursion vs. frequency vs. system output for a 12- and 15-inch loudspeaker. In the chart, it shows that a 15-inch driver cone only has to move half as much as a 12-inch driver to produce the same output.

To produce sound, we need to displace air. Displacement is calculated by the product of speaker cone area times the distance the cone can travel. In other words, bore times stroke. For the same displacement, more bore requires less stroke.

What is the punch line? If you want it louder, buy more speakers or subwoofers.

Driver Behavior in an Enclosure

The increase in the system Q caused by the addition of air stiffness in the enclosure can cause distortion if the Q is increased excessively. This increase in Q works against our desire for a low-distortion system. Making the enclosure too small increases the Q too much, and we wind up with a system that produces a great deal of output in a narrow frequency range. These undersized enclosures are often referred to as a “one-note-wonders.”

What causes this behavior? The one-note quality is a result of the increased energy storage and transference in the resonant system. The bass just keeps going and going – like our swing at the park.

Power Handling

In an acoustic suspension enclosure, cone excursion increases as frequency decreases. This increase in excursion continues down to the frequency at which the force of the spider and the box exceeds the force of the motor. At that point, the excursion level is limited, and we will not see the increase in excursion . The result: We protect the speaker from physical damage due to cone excursion beyond the design characteristics of the speaker.

Predicting the limits of cone excursion relative to frequency and power is relatively simple for a sealed enclosure. The volume of the enclosure is inversely proportional to the amount of power the speaker can handle when perceived from the standpoint of excursion. A small enclosure limits cone excursion a great deal at very low frequencies, but the system does not produce a lot of deep bass. A large enclosure allows the speaker to move further and produce more low-frequency output, but we cannot drive the speaker with as much power for fear of damaging it.

As we increase the volume of the subwoofer enclosure, the air inside has less “spring effect” on the subwoofer’s motion. This graph shows the increase in driver excursion as air volume increases in four different enclosures.

Acoustic Suspension Overview

An acoustic suspension speaker enclosure reduces bass output at a rate of -12 dB per octave below the resonant frequency. When you combine this roll-off with the cabin gain associated with most vehicles, you can get excellent and linear low-frequency extension well into the infrasonic region. Acoustic suspension enclosures are easy to calculate and to construct. They are very forgiving of minor errors in volume calculation.

Finally, it is worth remembering that acoustic suspension enclosures are not the lowest-distortion enclosure designs available.

When it comes time to design a subwoofer enclosure for your car or truck, visit your local mobile electronics retailer and discuss your requirements. They can help you choose a subwoofer and enclosure design that will give you a solid foundation on which to build your audio system.

Installing mobile electronics systems is not as easy as it used to be. In the “good old days,” cars were made from thick metal and didn’t have many electrical components. Modern vehicle construction makes use of the thinnest, lightest materials possible. These body panels are held together with non-conductive adhesives, and it seems that every square inch of our cars and trucks are packed with computers, sensors and modules. Even a task as simple as wiring an amplifier can become quite complex.

In this Best Car Audio article, we look at the importance of proper wiring techniques and materials, and the effect they have on the performance of an aftermarket audio system upgrade.

Power Delivery

This article is about installing a five-channel amplifier in a vehicle with a factory head unit. There are two important tasks when it comes to installing an amp: getting a signal to it and getting power to it. For an amplifier to produce power, you need to feed it power. The primary source of power in our vehicles is the alternator, followed by the battery. Most people focus on running a large conductor from the positive terminal of the battery to the positive terminal of the amplifier. While this is important, where and how the amplifier is grounded is equally important.

Quality installers will know the best locations on a vehicle to make a ground connection. They will know how to handle a vehicle with an aluminum or composite chassis. They will know how to recognize vehicles that are assembled with adhesives instead of spot welds. If you are installing a large amplifier, they will know how to upgrade the factory wiring under the hood to handle the extra current draw.

Protecting your vehicle is a part of installing power wire. In the unlikely event you get into an accident or something bad happens to your amplifier, the wiring and the equipment installed in your vehicle need protection in the form of a fuse. A good installer will install a fuse as close as possible to each source of power for the system. In most installations, this is near the main battery.

Some systems have secondary batteries and require additional fuses for proper protection. If you have the choice, a fuse provides better protection device than a circuit breaker. Fuses offer more surface area for power conduction. Also, there is absolutely no chance that a properly installed fuse could fail in a condition that may allow current to continue to pass.

Signal Integration

The audio systems in modern vehicles are becoming increasingly complex. Manufacturers (JBL, Infinity and Lexicon) are turning to suppliers like Bose and Harman for increasingly complex audio systems. Each of these companies employs highly trained engineers who spend months tuning each new system.

Trying to source an audio signal that will work with aftermarket equipment is becoming increasingly difficult at the same time. A properly trained installer will have the knowledge and experience to measure the signals in the factory system to determine if they can be used as is. If the signals are not acceptable in level, frequency response or bandwidth, your installer can recommend the correct component to correct them.

Your installer will also know to test each signal source across multiple functions. Ensuring that factory Bluetooth, navigation prompts and parking sensor warnings continue to work as intended is important to you being able to enjoy your upgraded audio system.

Noise Prevention

Dealing with factory computers, sensors, data networks and other high-current components can cause interference with the delicate low-level audio signals we send to our amplifiers. If you are not using good-quality interconnects that offer a twisted-pair design and appropriate shielding, you leave yourself open to picking up all sorts of strange noises. Likewise, choosing the right equipment is critical. You want to ensure that each component in the signal path has differential inputs to reject any noise that might be imposed on your interconnects, or the speaker wires running to the input of your amplifier.

The amplified signal coming from your amp is still subject to noise. Passive crossover networks can be notorious for picking up electromagnetic noise. Where your installer places the passive networks is quite important. An experienced installer knows what to avoid for your system to sound great and be noise-free.

Choice of Wiring Materials

There are two options for power and speaker wire – CCA and what most refer to as OFC. CCA stands for Copper Clad Aluminum. CCA typically is an inexpensive wire that is part aluminum and part copper. Aluminum costs less than copper, but it also does not conduct as well. You will usually see CCA wiring labeled with Gauge or GA when referencing its size. It is also worth noting that, unless the wiring you have chosen says AWG on it, there is no standard for the size of the conductor within the jacket.

Combine that with not knowing the ratio of copper to aluminum, and you run the risk of starving your amplifier for power. We have seen CCA 4 gauge wires that present almost four times the resistance as a proper 4 AWG conductor.

OFC stands for Oxygen-Free Copper. The term OFC has become the accepted slang term for all copper wiring. Properly sized copper wiring (using the AWG standard) offers the best possible power delivery to your amplifier.

Working on modern vehicles has its challenges, but those challenges come with rewards regarding background noise levels, convenience and features. Trust the installation of your audio equipment to qualified professionals. They have the experience to get the job done right the first time.

Installing mobile electronics in a vehicle is a balance of technical skill and creativity. From the seemingly simple task of connecting wires to the creation of a custom amp rack or subwoofer enclosure, each task requires the car audio installation technician to call upon many different skills. When it comes to installing audio gear in your car, many retailers offer packaged solutions at different performance levels for their clients – this is often called the Good, Better, Best approach. In this article, we look at a few examples where this approach is commonly applied and examine the benefits for each.

Door Speaker Installation

It sounds simple, doesn’t it? Take off the factory door panel, unscrew a speaker, connect the new one, then screw it in place. Finish up by putting the door panel back on. For the average mobile electronics retailer, this would just barely qualify for a “Good” installation. With the speakers connected and installed, the installer typically will have a listen to the system before putting it all together to confirm all the wiring is correct. If you require a speaker adapter, the shop may offer to supply one made from painted wood or crafted from HDPE or ABS plastic. Always take the plastic adapter. Wood will swell up when it gets wet.

For those looking for a “Better” installation, several companies offer speaker mounting baffle rings. These are foam rings that surround the speaker and seal the mounting surface to the back side of the door trim panel. This ring can help with the transfer of sound energy into the vehicle and is likely to reduce the chances of buzzes and rattles. Your installer may also place a sheet of damping material behind the speaker – 12×12-inch pieces are common. This material helps to damp the metal to which the speaker is mounted and ensure there is no gap between the speaker and the mounting surface.

In a “Best” quality installation, the installer will cover the entire surface of the door in a high-quality damping material. Sealing up the access holes in a door panel can dramatically improve the low-frequency response and overall efficiency of the speakers you are having installed. In fact, money spent on proper damping offers a bigger gain in performance than an equivalent upgrade in the quality of speakers.

Several companies offer composite damping solutions that combine damping with a layer of closed-cell foam. This type of damping material offers a further reduction in buzzes and rattles, and improvement in sound absorption.

You may opt to have damping material installed on the outside door skin while the trim panel is off. Damping the outer door skin will further reduce the transfer of outside noise into your vehicle, making your audio system easier to enjoy. If you are using a moderate- to high-power amplifier, you may also opt to have new speaker wires run into the doors.

Subwoofer Enclosure

One of the first upgrades you should do to your audio system is to add a subwoofer. Almost every factory audio system, even one that includes subs, sounds anemic and weak.

When it comes to the choice of subwoofer enclosure, the options are nearly limitless. The most basic of subwoofer enclosure solutions is to pick a pre-fabricated enclosure from a catalog, have your installer install the sub and plunk it in your vehicle. This solution doesn’t qualify for our standard of “Good”, but it works, and it’s better than not having a sub at all.

Choosing to have your retailer design an enclosure specifically for the subwoofer you have chosen and the exact space you require moves us up to the “Good” standard. The enclosure should be made of 3/4″ MDF and finished in a material that matches your vehicle. It should maximize the available room in your vehicle reasonably well.

The move to the Better level may take different directions, depending on your vehicle. Fiberglass or Stack-Fab enclosures can further maximize the available space in your vehicle. If constructed correctly, these enclosures can be more rigid thanks to additional bracing. This bracing results in better performance. At the “Better” level, your installer may choose to incorporate some cosmetic accents. Including a trim ring around the sub in an accent material is pretty common.

At the “Best” level, the enclosure design will be topnotch! Your installer may even choose to measure the Thiele-Small parameters of your subwoofer before starting work. The enclosure will be extremely rigid and well-reinforced internally.

Your installer may choose to line or stuff the enclosure with materials like Dacron or foam. Cosmetics will also take a leap forward at this level. Having the enclosure trimmed flush to the sides of the vehicle is a must to make it look like it came from the factory. Your installer may choose to use vinyl or leather on the visible parts of the enclosure to further improve the match with factory styling. A product or vehicle brand or logo may be incorporated into the design as well. At the Best level, anyone who sees the resulting creation should be immediately impressed.

Design and Cost

There is no limit to how creative your installer can get with the installation – it’s all governed by how much you want to spend. At the higher end, the installer may provide drawings or sketches of the finished product. You will probably have to pay for this design time. That said, many shops will credit some or all of that back to you as part of the final cost.

The top installers around the country charge upwards of $100 per hour for custom work or more. Their experience and creativity allows them to be very efficient in executing their ideas, and the work behind the scenes is often equally exemplary. Attention to detail for wiring, product mounting with Nutserts or stainless steel hardware, and proficiency in system design and tuning are all part of getting the Good, Better or Best value for your money.

Among the most under-appreciated components in any audio system are the speakers. You could be using the best source unit on the planet, an amazing amplifier, and the most esoteric of interconnects and speaker cables – but if you don’t have great speakers, you still won’t have great sound. Your speakers are the only link between your electronics and your ears, so choosing great speakers is critically important to reproducing great sound. This article discusses what you get when you spend more money on speakers.

More Power Handling

Several factors limit the ability of a speaker to convert an electrical signal into speaker cone motion. One such limit is thermal capacity – just how much heat the voice coil, tinsel leads, former and cone can handle before one of them fails. Heat is the number-one enemy of speakers. Most of the power you send to your speakers is converted to heat rather than to sound – in fact, probably 95% or more is converted to heat.

As the quality of speakers increases, you often encounter a larger voice coil and better cooling technologies. These features, coupled with tighter tolerances around the voice coil, result in a speaker that can absorb more energy without failing.

More Excursion

Often tied directly to how much power a speaker can handle is the distance the speaker cone can move forward or back. This specification is called excursion. For most speakers, the specification for excursion is called Xmax. Xmax is the distance the cone can move in one direction without the voice coil moving out of the magnetic field, and the measurement is typically provided in millimeters.

A second and often equally important specification is Xmech or Xsus. These specifications describe the physical limit of how far the cone can move, based on the design of the suspension (spider and surround). A speaker can be pushed past the Xmax limit, but as this happens, distortion occurs. When a speaker cone reaches its physical excursion limit, distortion will spike even higher. When it comes to speakers, there is no good distortion, so operating them within their physical limits is critical to producing accurate sound.

Why is excursion important? When combined with the ability to handle more power, a “better” speaker will play louder when provided with more power. The same features also help to reduce a phenomenon called power compression. Power compression is a reduction in the efficiency of a speaker as its components heat up. The key drawback to power compression is that when the music gets quieter, you turn the volume up, thereby sending more power to the speaker and accelerating the heating effect. In no time, the speaker will fail.

Excursion Linearity

It’s one thing for a speaker to have good power handling and excursion characteristics. It is equally important that the speaker remains linear throughout its excursion-based operating range. All speakers change in their characteristics as excursion increases – a great speaker minimizes these.

Let’s look at a common problem with “simple speakers.” One of the characteristics that limit the high-frequency response of a woofer or midrange driver is inductance. The voice coil of the speaker has some natural inductance because, well – it is a coil of wire. This inductance is increased when we place the voice coil around the T-yoke of a speaker.

This is where the problem occurs: As the coil moves forward, some of it may leave the T-yoke, which will reduce inductance. As the coil moves rearward, inductance may increase. The result is that the speaker has different frequency responses depending on where it is within its range of excursion. Truly excellent speakers use technologies to minimize these effects. The result are speakers that sound just as good at low to moderate drive levels as they do when being pushed hard.

More Frequency Response

This is a bit harder to describe, because sometimes the improvement from a basic to a mid-priced speaker, or a mid-priced speaker to a high-end one, is extended frequency response. More often, it’s smoother frequency response. Better-quality speakers are, ideally, designed to reduce distortion caused by cone resonances, suspension nonlinearities and magnetic field imbalances. As you spend more on speakers, you will see that peaks in their frequency response, especially in the midbass region, are tamed.

Many great speakers still exhibit some cone resonances at high frequencies. As long as the speaker you are using in the adjacent band will play low enough, those peaks are not critical.

Reduced Distortion

When a speaker designer combines an appropriately damped and rigid cone with a carefully designed motor and suspension, the result is a speaker that produces less distortion. Some distortions are very subtle, while others are quite pronounced. Speakers exhibit both even- and odd-ordered harmonic distortions, depending on what component or design issue is to blame.

If you have read our article on distortion, then you know that it is the effect of adding content that was not in the original program material. Harmonic distortion results in even or odd multiples of a specific frequency.

When you hear an amazing speaker, the difference between it and an average speaker is clarity. Smooth frequency response and a lack of distortion make each sound the speaker produces more faithful to the recording. Voices will sound more realistic. Instruments will sound more natural. Complex passages will become easier to understand.

It is also critical to point out that distortions cannot be removed from a signal or sound once created. No amount of equalization can extract those harmonics. Yes, you can reduce their level, but you also reduce the level of original signal information at those same frequencies. The only solution is to use a speaker that does not introduce distortion.

The Right Tool for the Job

Another item that differentiates a good speaker from a great one is its design in terms of application. Let’s use a typical 6.5” midrange/midbass speaker as an example. If the speaker is designed to work in a typical door or rear deck-style installation, the Thiele-Small parameters for that transducer will be optimized for that application. If you attempt to put that speaker into a small kick panel pod that has only 0.1 cubic feet of air space, you will choke it. The low-frequency response will be dramatically reduced; typically, a bump in the midbass region will occur, and it will likely not sound very good. Most 6.5” speakers need an enclosure volume of about 0.6 cubic feet, and some want closer to 1.0 for smooth frequency response.

How do you look for a speaker designed for the right application? That is product knowledge that a properly trained mobile electronics retailer can provide. Do you need a midrange that will work in a small A-pillar pod? Do you need a woofer that will work in an infinite baffle application? Will your midbass driver be used with a subwoofer, or do you need one that will be the sole source of bass in the system? Knowing the intended application for a speaker ensures that the system designer will use it appropriately.

Are More Expensive Speakers Always Better?

Does price always determine performance? In the upper echelon of any audio industry, the rewards for spending exponentially more money diminish. That is to say, the improvement you get from spending $500 on a set of speakers as compared to $200 may not be as dramatic as the difference between $2,500 and $2,200.

Every speaker manufacturer wants you to buy their speakers. They all work hard to come up with great marketing programs to make you want to buy their products. Your goal in choosing an amazing speaker is to ignore the story and listen.

The best way is first to establish a reference. Listen to the best speakers you can find. Don’t worry about the price. You simply want to understand what is available. Then, choose your price point and listen to something in that range. If you can accept the differences, then proceed. If you can’t, re-evaluate your needs or your budget. You can’t get that extra level of clarity, dynamics and detail any other way.

According to a AAA survey, the average American drives for about 45 minutes each day. If you compare this time to an eight hour work day, that’s 10% of your work day, on top of the hours you are at your desk. This time is not an insignificant number. If your job involves being on the road, then your time spent behind the wheel can represent half of your day. Being able to be productive while in your vehicle is not only convenient, but in some cases, mandatory to get all the work you need to get done in one day completed. Modern smartphone integration comes to the rescue with Apple CarPlay.

Apple CarPlay History

Apple recognized the need to give people the ability to use their phones in a safe fashion while driving back in 2010. The feature was called iPod Out. BMW announced that it would include iPod Out at the WWDC that year. The concept was that BMW would provide a way for its vehicles to ‘host’ specific applications. The information would be displayed on the factory screen while providing button press and knob rotation information back to the radio.

The next evolution was the introduction of Siri Eyes Free in some Honda Accord and the Acura RDX and ILX models in 2013. Siri Eyes Free is a way to make use of the Siri voice recognition function that Apple Introduced with iOS 5 and the iPhone 4S in October 2011. Apple has marketed Siri as a personal assistant. It allows you to talk to your Apple device to make phone calls, send text messages, set reminders and choose the music you want to hear. Using Siri Eyes Free is simple- press and hold a button on your car radio, wait for the tone, and then speak.

Siri will listen to what you said, convert that to a command and execute it, all without you needing to take your eyes off the road.

Between the time that Apple announced iPod Out and the Geneva Motor Show in March of 2014, Apple was working on the next generation of automotive integration under the code name Stark. At the Geneva Motor Show, they announced ‘iOS in the Car.’ Later that year, Ferrari introduced the new FF model with a fully working version of Apple CarPlay. A few months later, Hyundai announced the Sonata would also feature CarPlay. Most automobile manufacturers have CarPlay available on their mid to high trim level vehicles now.

Apple CarPlay Interface Overview

Apple’s current marketing touts CarPlay as ‘The Ultimate Copilot.’ The features are designed to allow you to communicate with family, friends, and coworkers without significant distraction. The basic feature set of CarPlay includes making and receiving phone calls, choosing the music you want to listen to, getting navigation instructions and sending and receiving text messages.

Apple has worked hard to ensure that the above functions are usable without unnecessary distraction. As soon as you plug your phone into the USB port of your radio, CarPlay launches automatically.

CarPlay does not display incoming text messages on the screen of the radio. Messages are read aloud to prevent users from looking at the dash. However, there are no options presented when asking Apple Maps to plan a navigation route.

Selecting music to play is as easy as requesting the track title, artist or even genre of music you want to enjoy. CarPlay will start playing what you want right away. Apple has also included support for Apple Music- a streaming service powered by iTunes. CarPlay also supports Apple Podcast and Audiobooks. You can select the episode you want to listen to via the touchscreen interface, then play, pause or skip 15 seconds forward or back. Apple CarPlay provides support for several third-party applications including Pandora, Spotify, iHeartRadio, Audible and MLB At Bat.

Apple has released information to application developers in order to allow for the creation of more third party applications. You will see more and more third-party applications added to the CarPlay interface as time passes. Apple will, of course, be selective in their approval process, so don’t expect to see competing navigation applications any time soon.

The Future of Apple CarPlay

Unveiled by BMW in October of 2016, future iterations of CarPlay will function wirelessly. The 2017 BMW 5-Series sedans, when used with an iPhone 6 or newer, will allow users to use CarPlay without the need to plug in the Lightning connector. Wireless CarPlay communicates over a Bluetooth data connection.

Apple is tight-lipped about future functionality of CarPlay. There have been rumours about vehicle function control like remote door lock control, remote starting and trunk release, but so far nothing is set in stone. Another rumored feature is the ability of your phone to remember where you parked your car once you have arrived at your destination.

Apple has led the industry with safe and convenient integration of your smartphone to your vehicle. The future of ‘connected cars’ promises to allow us to share information and offer better communication while remaining safe. If you are interested in adding CarPlay to your vehicle, visit your local mobile electronics specialist retailer. They can show you what options are available for your vehicle.
