5 Tips for Doing Car Audio Sound Deadening the Right Way

All of the right automotive sound deadening products are not created equal. Some are composed of cheaper, less effective materials that can peel away over time. Others just don’t have the adhesive necessary to permanently hold up in a car’s high-temperature environment. Unfortunately, when you purchase a discount deadener product you may be inadvertently buying something that will do more harm than good by deteriorating over time or quickly losing surface adhesion. This is a problem worth avoiding because regular deadener replacement will cost you much more in labor and materials than if you had started with quality products from the get-go. Here are some things to consider when shopping for deadener and sound insulation products:

1. Adhesive

Adhesives are very important for sound deadening products because they give them the ability to permanently adhere to your car’s surfaces. Of course, many sound insulation products also use adhesives, but applying these materials can be a challenge in your car because most have a tendency to stick to themselves no matter what surface they’re put on. So you’ll need an extra set of hands or an ultra-hydrophobic surface (such as a dish towel) to help you apply the product without causing it to peel away and fail before it even has a chance to do its job. On the other hand, some sound deadener products get their own adhesive solely because of their unique design.

2. Durability

One of the most important things to consider when purchasing sound deadener is durability. The reason why you should consider this aspect is because it can be easy for some products to end up with a short lifespan due to exposure to high temperatures or other environmental factors. If your car’s doors regularly get left open in the sun or your rear hatchback is used as a workshop at all times, then it’s likely that you’ll need to replace these products every year or two at most on average, which will cost you something worthwhile. But if you plan on keeping your car clean and protected from the elements, don’t worry about durability since your deadener should see many years of service before requiring replacement due to wear and tear.

3. Cost

The price of a given deadener or sound insulation product should be factored in based on the size of your car and the amount of work that has to be done to properly install it. For example, a large SUV or pickup truck might require multiple sheets worth of deadener materials for optimal performance, which will likely increase overall costs. On the other hand, if your car doesn’t have much surface area to cover or you purchase products from an auto parts store that offers sound deadener coupons and discounts, then your costs could go down significantly.

Know the deadener’s properties. A good installer, like a professional electrician, doesn’t purchase cheap electrical wire or components, so why would you use cheap automotive sound deadening material? There is no substitute for quality materials and it’s important to understand the varying properties of both the backing material as well as the adhesive. Some materials will not hold up in high temperatures so they will lose their effectiveness over time. Others just don’t have the strength or adhesion needed to give you a solid bond with your metal panels. In both cases you’ll be replacing your installation more often than if you had used quality material in the first place.

Is sound deadening a car worth it?

Most people buy sound deadening to improve their car’s “sound proofing” but if you think about it, that is the wrong reason. It’s actually the other way around – solid soundproofing improves the quality of your audio system (CDs, DAB, FM) while deadening robs your music of its life. Sound deadening products fill in all the wrong places, making it difficult for your sound system to properly “speak” and hold up its end of a conversation. Quality materials will reduce noise in more than one area which means you can take advantage of each component in an audio system to create complete listening environments in each seat of your vehicle. When you install quality sound deadening you’re not just “deadening” for the sake of it. You’re improving the sound quality of your entire audio system.

The next step after choosing a location is to choose your solid/yield point. When you’re setting up your car, pay attention to component placement and ensure that both front seats have access areas for their respective components. If you’re wanting to deaden the whole interior, make sure that all of your material (the carpet, foam, etc.) is nice and thick so that it will deaden or “mute” bass frequencies without over-exerting itself.
