Frequently Asked Questions
What is sound deadening and how does it work?
Sound deadening materials are dense, viscoelastic sheets (usually butyl rubber with an aluminum layer) that adhere to your vehicle's metal panels. They add mass to thin sheet metal, converting vibration energy into heat, which dramatically reduces road noise, rattles, and resonance.
Will sound deadening improve my audio system?
Absolutely. Door deadening is one of the best upgrades for speaker performance. It turns your door into a proper speaker enclosure, improving bass response and clarity. Your music sounds tighter and more defined, especially in the mid-bass frequencies.
What areas should I treat first?
Doors give the biggest improvement for audio quality. Floor pans reduce road noise and tire hum. Trunk/hatch areas help subwoofer performance and reduce rattles. We can treat specific areas or do a full vehicle for maximum results.
What brands do you use?
We use Dynamat, Noico, and other premium butyl-based materials. These properly rated products outperform cheap alternatives and last the life of your vehicle. No asphalt-based products—only quality butyl rubber compounds.
