What is Dynamat?
A: Dynamat is a thin, flexible, easy to cut and mold sheet that actually stops noise causing resonance and vibration, by using visco-elastic qualities that promote vibro-acoustic energy conversion. In short, that means noise becomes silent energy.

How Much bass increase can I expect to get with a Dynamat Trunk Kit?
A: While results vary from vehicle to vehicle and depend greatly on the installation, typical results have yielded a 3dB increase in Sound Pressure Level (SPL) bass output from a normal installation.

Where can I buy Dynamat?
A: Dynamat is sold in over 5,000 stores in more than 50 countries worldwide. To locate a dealer in the US click here.   Check our International Distributor List to find information on buying internationally.

What kind of tools do I need to install Dynamat?
A: Installing Dynamat requires only a few tools:   razor knife or scissors, roller tool, rags and a solvent- based cleaner (rubbing alcohol also works). You also need basic hand tools for the disassembly and reassembly of your vehicle.   Consult your owner's manual or vehicle's shop manual for instructions. Review the Car Audio Installation Instructions before starting.

My floor board gets hot during long drives.   Is there anything I can do?
A: Heat coming from a hot exhaust or headers is a common problem.   Fortunately, Dynamic Control has a solution.   First apply Dynamat Xtreme to the floor and firewall, then install Dynaliner, both underneath the floor's carpet. This process is outlined in Dynamat Floor Applications.

What part of the vehicle should I do first?
A: We recommend applying Dynamat to any surface you can easily reach.   In general, we recommend treating your vehicle in the following order: Doors, Trunk, Rear Deck, Floors, Roof, Hood, then Fenders.

Dynamic Control makes different products.   Which is best for me?
Dynamic Control provides solutions for most vibration, noise and heat isolation problems.   See the products section for more information on specific solutions for each part of your vehicle.

How does Dynamat stop road noise?
As a car operates, it generates noise. This noise is caused by the transference of energy (vibration) from the internal components and from the road to the chassis   of the vehicle. The chassis (doors, floors, roof etc.) transforms this vibration into audible noise. Dynamat transforms the energy (vibration) into silent energy.

How much will Dynamat quiet my car?
Even a small amount of Dynamat can cause a profound noise reduction.   For example, applying Dynamat to the doors of your vehicle can reduce road noise from 3-6dB!.   Complete coverage of an average vehicle can reduce road noise 9, 12 even as much as 18dB.

How much Dynamat do I need to use to be effective?
You can apply Dynamat in patches (25-50% area coverage) to keep a specific panel from resonating or you can apply it over an entire area (such as the floor, doors, or trunk) to create a sound barrier and vibrational damper.
