Dynamat Extreme Bulk Pack

Having a hard time hearing your car's sound system over the road noise? Dynamat Xtreme keeps the noise out, so you'll hear more music using less power — effectively increasing your amplifier's output! This sheet metal vibration damping material (a butyl composite with a layer of aluminum) conforms and fuses to automotive body surfaces such as floor pans and doors.

The 10455 bulk kit includes 9 sheets of Dynamat Xtreme, for a total of about 36 square feet (a car door requires about 5 square feet). Designed especially for high-temperature areas and high sound pressure level situations, Dynamat Xtreme offers four times the damping power of Original Dynamat, thanks to its energy-reflective aluminum layer.
