Product Description
When driving, the body panels of your Defender vibrate and create noise. The faster you drive, the louder that noise will be. At 70 mph, a typical automotive noise level reaches 85 dB. This will interfere with the sounds inside your vehicle, like your stereo, cell phone calls and conversations by affecting the dynamic range of these sounds. If you want your music louder, you can turn up your stereo, but that only increases volume. It does not give you back the dynamic range you have lost. One of the main culprits of this noise is your vehicle’s doors. Without Dynamat Xtreme, vibrations resonate and echo through the hollow inner door cavity.
Since much of the noise that comes from the road enters through the doors, installing the Dynamat Xtreme Door Kit creates a sonic barrier that converts noise-causing vibration into silent energy. By reducing the road noise, the Dynamat Xtreme Door Kit can increase the dynamic range of the sounds in your car, which can effectively double your vehicle’s amplifying power! You get louder sound from your car’s audio and less annoying noise from outside your vehicle.
The Dynamat Xtreme Door Kit does not require any special equipment, so it is very simple to cut and install. It will conform easily to your vehicle’s inner and outer door skins, and the sticky butyl rubber will adhere and stay in place without any special surface prep. For best results, install the Dynamat Xtreme Door Kit with one of our Dynamat roller tools. Use the Dynamat Xtreme Door Kit on your doors to hear the Dynamat difference.
Contents: (4) 12? x 36? (305mm x 914mm) pieces of Dynamat Xtreme. Kit includes enough material for two standard Defender doors.
For proper installation, use one of our Dynaroller tools. Self-adhesive.
