Sound deadening: a quieter car and tighter bass.

Where it helps most

• DoorsReduces rattle and gives door speakers a more solid mounting surface for better midbass.
• Trunk and cargo areaControls vibration from subwoofers and cuts road noise.
• Floor and firewallReduces road and engine noise that reaches the cabin.
• Roof and rear panelsCuts drumming and resonance.

Do you need it?

If you are installing speakers or a subwoofer, deadening the doors and the trunk is one of the most cost-effective things you can do. It is also worthwhile on its own if your car is loud on the highway. The amount of work and material depends on the vehicle and your goals.

Materials and installation

Sound deadening comes in several forms, including vibration-damping sheets for metal panels and foam layers for blocking sound. Products such as Dynamat and Dynaliner are examples of the materials used for this kind of work. Different areas of the vehicle call for different materials. The right mix depends on your goals: tighter bass, a quieter ride, or both.

Installation takes time because panels must be removed, the metal cleaned and the material applied and rolled flat. We plan it so you know how long your vehicle will be with us.
