Dynamat Xtreme quiets annoying road noise, improves a speaker’s dynamic range, and makes for a more comfortable driving experience. You can quieten the noise, and get better sound. Without Dynamat car noise can prevent you from hearing music, phone calls, conversations and your GPS. As the speed of the car increases, so does the noise on the road. With Dynamat installed, you can relax and enjoy the time in your car. The music from your stereo sounds clean crisp and louder. Phone calls and conversations can now be heard. With Dynamat, you get less noise, a luxury ride and incredible sound for the ultimate car. Adding Dynamat to your vehicle doors is the easiest way to reduce the most noise and vibration. Without Dynamat, the vibrations resonate and echo through the hollow inner door cavity. With nothing to reduce the vibrations, you are left with the constant and aggravating road noise. Dynamat extreme is a thin easy to install, space age plastic, wiht an aluminium alloy skin. It enforces your car's body panels and converts noise causing vibration into silent energy. By installing Dynamat on your Kit contains four 305mm x 914mm pieces of Dynamat Xtreme to reduce road noise so you Hear More Music!™. Kit includes enough material for two standard size doors. For proper installation, use one of our Dynaroller tools. Apply the Dynamat panel surface with a Dynamat roller tool. Take the roller tool and work the Dynamat into all of the contours of the metal panel. Using a razor knife, poke holes in any air pockets that may have formed between the panel and the Dynamat. Work the air out with the roller tool. Eliminating air pockets will ensure lasting adhesion of the Dynamat to the panel, giving you maximum damping efficiency.
