We all know that having sound deadening installed in your car or truck is a great way to improve its comfort while allowing your stereo upgrades to sound better. In this article, we’ll look at some of the strategies for adding sound deadening. We’ll talk about different areas of the vehicle and the benefits associated with treating those surfaces. Based on this, you can decide how to get as much value and performance from a damping material investment.

Why Add Sound Deadening

Sound deadening comes in several solutions. For this article, we will focus on what’s known as constrained-layer damping (CLD). In short, these are sheets of dense butyl rubber that are bonded to a flexible layer of aluminum. The CLD is intended to be applied to your vehicle’s metal panels to add mass and reduce the panels’ ability to vibrate and transmit sound from outside the car or truck to the interior.

Sound deadening can be applied to almost any surface to help prevent noise from the engine, exhaust, transmission, tires or wind from getting into the vehicle.

Some damping materials like SoundShield add a layer of closed-cell foam to the aluminum layer for additional energy absorption. This foam also reduces the chances of wiring harnesses or door actuator rods from rattling and making noise as you drive.

Sound Deadening Car Doors

One of the most dramatic upgrades you can make to your vehicle’s comfort is to have the doors treated with sound deadening. Here, two approaches offer different benefits. The outer door skin, the one you see when you look at your car or truck from outside the vehicle, is a large and relatively flat surface. If you tap on it, you can feel that the metal is somewhat flimsy. Having damping material added to the back of this panel will dramatically reduce noise transfer. Since you sit close to the door, the results are quite noticeable.

The second surface that can benefit from deadening is the inner door skin. This is the metal you’d see when the technician working on your car or truck removes the plastic trim panel from the interior side. This is another large surface and is often very flat.

Aside from keeping road noise out of the interior, sealing the door skin can have a dramatic effect on the performance of a door-mounted speaker. Typically, large openings in the metal allow access to the window regulator (the mechanism that raises and lowers the window), the door handle and the latch parts. Left open, the sound coming from the back of the speaker will mix with the sound coming from the front and cancel. Sealing these openings will dramatically improve lower midrange and bass performance from the audio system. This increase in output means your technician can reduce the power sent to the speaker so it will last longer. Likewise, a reduction in how hard a woofer has to work will reduce distortion and improve clarity.

Floor and Firewall Deadening

Modern vehicles are designed using computers to deliver a balance of strength and weight to make the vehicle drive well. Most automakers work hard to save every ounce so that fuel economy is optimized. You’d be surprised how much noise from the engine and transmission comes into the vehicle through the firewall and floor. Of course, the answer is to have these surfaces treated with high-quality deadening material. The process does require some significant work to remove the center console, seats and carpet, but it’s well worth the investment.

Pickup Truck Noise Control

The back wall of a pickup truck is another surface that can transmit a lot of sound energy into a vehicle. Though it’s blocked from wind noise, it still transmits drivetrain, exhaust and tire noise. Treating the back wall is a great way to improve the comfort of these vehicles.

Sound Deaden Your Vehicle’s Roof

Easily the biggest and probably the flattest panel in a vehicle is the roof. Whether you have a short-cab pickup or an SUV with 40 square feet of metal, wind noise will transfer into the vehicle through this flat surface. Having the roof liner removed can take some time, but the effort is worth the expense to improve your vehicle’s background noise level. With microphones for Bluetooth hands-free systems typically installed up high in the car, cutting down on noise will dramatically enhance an outgoing phone call’s clarity.

Trunk and Cargo Area Sound Control

If you have a car with a trunk, especially if you are having subwoofers installed there, controlling panel vibration and rattles will make a huge improvement to the performance of your audio system. Likewise, road noise and sound energy from the exhaust system will be reduced by treating the floor, fenders and hatch or trunk lid.

Picking the Right Deadening Material

As you can see, different areas of the vehicle need to be upgraded for different reasons and with different results. What remains constant, no matter where your technician is working, is the need to use high-quality materials. On surfaces that are vertical or where the deadening will be installed upside-down, proper surface preparation is paramount, and using a product with excellent adhesion qualities is a must. Avoid deadening that is bitumen- or asphalt-based as they can soften and come loose in high-heat conditions.

You’ll want to choose a shop and technician with the experience and training to remove the interior components of your vehicle in a way that prevents any potential damage and ensures that the vehicle can be reassembled properly once the work is complete. The last thing you want is to have clips or brackets that are loose, resulting in more noise added to the interior as you drive.

Having sound deadening installed in your car or truck is one of the best upgrades you can make to the vehicle’s comfort and your audio system’s clarity. Reducing background noise will make the subtleties of your music easier to discern. Likewise, if you have a hands-free Bluetooth system, the outgoing audio quality will be clearer. Drop by your local specialty mobile enhancement retailer today to inquire about having sound deadening installed in your car or truck.

A significant car audio system upgrade takes four items: a budget, great gear, expert installation and proper configuration. If you’ve read any number of the articles here on BestCarAudio.com, you’ll know we hold the importance of quality equipment, proper installation and expert calibration in the highest regard. Deciding how to distribute your budget should include that crucial final step that brings everything together. This article will look at what it takes to achieve an awe-inspiring listening experience in your vehicle.

Establish Your Car Audio Budget

We know that everyone has different budget constraints and equally diverse expectations for upgrading their car audio system. Some are willing to spend thousands of dollars to achieve the most accurate, realistic listening experience in their vehicle. Conversely, many want the most bang for their buck and seek out the biggest upgrade possible from a small investment. Neither approach is wrong, and your local specialty mobile enhancement retailer can typically work with either end of the spectrum.

The key to getting the best value is to be clear about your expectations and how much you want to spend. If you want your car audio system to sound as though you’re sitting at the mixing console at Abbey Road Studios in London, England, but have a budget of $1,500, you’re going to be disappointed. Yes, the shop can make your system sound much better, but that last bit of sparkle, detail and transparency will likely be missing.

Be open and upfront with your budget. The product specialist designing your sound system can work backward from your budget to help you get the best value for your investment.

Avoid Used Car Audio Equipment

A friendly word of warning, if we may: It’s tempting to start shopping around for deals on previously enjoyed equipment to achieve a higher goal than your budget would allow. Most of the time, these efforts turn out fine, but surprisingly often, they end up being frustrating. It’s nearly impossible to know if a set of speakers has been abused and the voice coils are on the brink of unwinding. You can’t tell if an amplifier has been exposed to vibrations because of improper installation, and a component is on the verge of breaking loose. For a head unit, CD mechanisms have a finite life span; for the better units on the market, finding replacement parts is difficult.

If the shop you’re working with will accept third-party products, there will likely be an additional charge to test them before they are installed. In most cases, the installation warranty doesn’t apply to removing and reinstalling those components should they fail or have issues.

Choosing the Right Car Audio Upgrades

Just as asking “What’s the best car audio system?” is a relative question, finding the best products for your system is difficult if you aren’t experienced in auditioning audio equipment, even for those that often have a surprisingly low benchmark for what sounds genuinely accurate. Accuracy is the key word here. Any brand that describes its gear as having a “sound” or “style” has missed the boat in terms of understanding what audio equipment should do.

High-end amplifiers should amplify the audio signal. There shouldn’t be “warmth,” and they shouldn’t sound “smooth.” The signal that goes in should be increased to drive a speaker. Speaking of speakers, they have a similar task. They should transform an audio signal into sound with the addition of as little distortion as possible. Speaker systems should be designed so that the frequency response and dispersion characteristics of each driver compliment those operating in adjacent bands. You don’t want a 6.5-inch woofer and a ¾-inch tweeter working together. The woofer becomes too directional before the tweeter starts playing.

Expert Installation Is Crucial

Installing car audio equipment properly requires a few essential skills. First, the technician needs a thorough understanding of the laws of physics, including AC and DC theory and acoustics. They also need excellent problem-solving skills, excellent mechanical skills to construct adapters and mounting panels, and a certain amount of artistic flair to make it all look as though it belongs in the vehicle. Finding someone who excels at all of these criteria is difficult. Often, you’ll need to visit more than one shop to find the right match before you let someone start modifying your expensive vehicle.

Proper component installation doesn’t need to be fancy; it needs to be reliable. An amplifier will sound the same bolted to a piece of extruded ABS or a welded steel bracket as it would to edge-lit plexiglass or carbon fiber. Don’t fall prey to fancy designs while missing out on the opportunity to use higher quality equipment. Sadly, we see this all the time.

Proper System Calibration Is the Most Important Step

If you are expecting to hear Diana Krall’s voice as though she were really in the car with you, then your car audio upgrade is going to need a properly calibrated digital signal processor. No matter how great your installation is, how fancy a source unit you’ve purchased or how impressive your speakers are, your audio system won’t sound right without proper equalization and level setting. The bare minimum here is that each channel in the vehicle is equalized to remove the effects of resonances and cancellations in the vehicle. You will also need to decide if signal delays should be used to optimize the soundstage for a single seat (the driver’s seat) or both front seats. The latter may require some changes to the system design, so this decision is crucial to the design stage.

Your technician will need a calibrated microphone to properly tune the audio system. He or she will also need to have a thorough process to complete the task. Setting up a DSP properly isn’t an art, and it doesn’t take unnatural talent. It’s a scientific process. With that said, it does take practice to execute efficiently. Knowing what characteristics of the response need to be addressed and what needs to be ignored or dealt with by changes in crossover points takes proper experimentation. There’s no guessing or voodoo involved.

Before you commit to having a sound system installed and calibrated, you will want to audition several systems that the installer has completed. Hopefully, and expectedly, the shop will have a demo vehicle or two that you can audition. If not, ask if they can put you in touch with a previous client.

The cost of the calibration process is an important part of the overall car audio budget. Don’t be shocked for there to be at least one to two hours’ worth of labor dedicated to the process. For a four-way system or one designed for two-seat imaging, three hours isn’t at all unreasonable.

How Do I Know if the Calibration Is Correct?

We hear horror stories about signal processors being installed but not configured properly all the time. Here are a few things you can listen for while auditioning the demo system before you commit to letting a shop work on your vehicle.

The audio system should produce a stable center image. This means the voice of a performer that would be center-stage should be reproduced in the center of your windshield. The voice shouldn’t move left or right as the pitch changes. If the system is calibrated extremely well, the image should be small, about the size of a softball. Sounds on either side of the center image should be equally focused. If there is a guitar, backup singers or a saxophone, they should be placed accurately, and the source of the sound should be easily discernable.

Some music enthusiasts prefer to have the music wrapped around them with an equal amount coming from the back as the front. In this case, you will want the center image to be focused on you, the driver. There should still be a realistic balance of left and right instrument placement on either side of that position. If you like this style of listening (which is akin to a great seat of headphones), be sure to let the product specialist know before the system design begins.

The overall tonal balance of the system should sound natural. No part of any performer’s voice should stand out. This applies to both treble and bass. Sibilance, or having too much emphasis on S sounds, could be a tuning issue or a distortion issue with your speakers. If it’s the latter, only better quality speakers will resolve the problem.

Deciding how much bass is right is tricky. We know bass is a lot of fun, so it’s not unheard of to have much more than would make a drum kit or upright bass sound realistic. This is another criterion that needs to be determined before the system design process begins.

It’s Your Job To Get the Most from Your Car Audio Budget

Unlike buying a set of speakers for your home audio system or a soundbar for your television, a car audio system needs to be designed for the speaker locations and size options in your vehicle, installed securely, safely and reliably, then calibrated for the environment so that it sounds excellent. It’s your job to define a budget, then seek out a specialty mobile enhancement retailer that can complete this car audio upgrade task professionally.

Just as we’ve looked at the Mustang in the past, it’s now time to check out the car audio and convenience upgrades available for the Chevy Camaro. As one of the veteran pony cars, the Camaro went on sale in September 1966 as a 1967 model. These midsize coupes have been synonymous with performance with models like the Z/28 and IROC-Z models offering impressive levels of power and performance at their time. The latest ZL1 1LE model with 650 horsepower would put supercars of the ’80s and ’90s to shame.

Camaro enthusiasts have sought to personalize and upgrade their vehicles with more power, more features and, of course, improved audio system performance. Whether you want to add seat heaters or a new radio to an older model, or you need better sound and more bass than the Bose systems in the fifth- and sixth-generation models offer, your local specialty mobile enhancement retailer can help.

Camaro Radio, Speaker and Amplifier Upgrades

For those with first- and second-generation Camaros, the first upgrade you would want to make to improve the performance of the audio system is to have a new source unit installed. The stock twin-shaft radios in these vehicles are as basic as it gets. Companies such as Custom Autosound and RetroSound offer modern source units with USB and Bluetooth connectivity in a design that will bolt right into the factory radio location. Many of these radios are available with options to add a SiriusXM satellite radio tuner module. The best part: You can add an external amplifier to these radios to dramatically improve the performance of a new set of speakers.

If you want better sound quality and more features, you have two options. You can have your local retailer cut the dash to make way for a single-DIN-sized receiver, or you can hide a radio in the glove box or under a seat. Sony offers an app for Android and Apple phones that will let you control all the important features of its modern Bluetooth receivers remotely.

If you’re considering a radio upgrade for a third- or fourth-generation Camaro, you have a few more options. The stock radio in these vehicles was, in most model years, a 1.5-DIN Delco unit. Kits and adapters are available to allow a single-DIN radio to fit with no modifications. If you don’t mind a little bit of customization, then a double-DIN multimedia receiver becomes an option. Having a large touch-screen to display navigation information or let you use Apple CarPlay or Android Auto will bring the technology of your vehicle in line with the latest cars and trucks to roll off the assembly line.

On fifth-generation Camaros from 2010 through 2015, many dash kits will let you upgrade the vehicle with a new double-DIN multimedia receiver. With items such as climate and heated seat controls built into the original dash, these replacements include hardware that replicates those features.

The latest generation of Camaros has moved to a relatively subtle version of the tablet-style radio. Unfortunately, this makes it difficult to install a new receiver. Fortunately, companies like NAV-TV make interfaces that will add high-quality, full-bandwidth pre-amp outputs to the factory radio so your technician can install aftermarket signal processors and amplifiers.

Custom Audio Upgrades

Even with a better radio, you will likely want to upgrade your Camaro with new speakers, amplifiers, a subwoofer and a digital signal processor. Adding a dedicated subwoofer system improves the impact and visceral experience of listening to music while driving. It also allows the system to play louder as the small speakers don’t need to provide bass.

New speakers will improve the clarity of your audio system and let it play louder than the factory speakers ever could. A nice set of components in the front of the vehicle can transform your commute into a studio-quality listening experience.

Finally, digital signal processors, whether a stand-alone solution or built into a high-power amplifier, allow your installation technician to calibrate the output of each speaker to work with its position in the vehicle and the acoustics of the environment. Proper system calibration is the only way to achieve realistic tonal balance and excellent imaging in a vehicle.

Window Tint Adds Comfort and Security

Another popular Camaro upgrade is automotive window tint. While many owners choose to add tint to enhance the style of their vehicle, it’s also a popular upgrade for those who want added security and a cooler interior. Modern ceramic and nano-technology films block as much as two-thirds of the infrared heat energy from the sun to help prevent your vehicle from turning into an oven. Darker films make it harder for people to see the contents of your vehicle, so your belongings stay safe. Finally, films with a strong adhesive make it harder to get into the vehicle for smash-and-grab thefts.

Remote Car Starters Make Driving More Comfortable

Whether you live where it’s below freezing in the winter or swelteringly hot in the summer, a remote car starter is a great investment in making your Camaro more comfortable. When it’s cold, starting your vehicle a few minutes before it’s time to leave will let the engine begin to warm up. In most cases, the starter system can trigger the rear window defroster and even a heated-seat system to make things more comfortable. When it’s hot out, letting the air conditioning run for a few minutes can drop the interior temperature by more than 20 degrees. If you or your passengers have respiratory issues, cooling the interior can be a godsend.

Lighting Upgrades make Driving Safer

Whether you have a classic Camaro or something just a few years old, new headlights and auxiliary lighting can make driving at night much safer. If your car came with halogen bulbs, then new HID or LED upgrades can provide as much as three times as much light on the road. Many companies offer replacement light assemblies that include colored accent lighting to add extra style to your muscle car.
