For clear, crisp bass without the rattle, use the Dynamat Trunk Kit. Adding Dynamat to the vehicle, especially the trunk, results in higher Sound Pressure Level (SPL).
Dynamat is self-adhesive, and the easiest-to-apply, thinnest and lightest material for adding sound pressure reinforcement to your car's body. When the panels don't rattle and balloon, you get higher SPL and tighter, louder bass.
The kit contains five 18" x 32" sheets of Dynamat Xtreme for the trunk floor, side panels and trunk lid, for the ultimate bass and road noise reduction.
