Pack a lunch when you tackle this project boys.. its a doozy!! Month in going great so far definetly did what I purchased it to do. 2000 chevy with two p3 10s every bass drop sounded like an old firebird with loose trunk bolts. Threw this on the back walls floor underneath the speaker and the doors.. all that energy is now in the cab with me instead of getting lost in rattling metal!! Love it!!! Left a few pieces outside after I was done rained like hell on them so water doesnt hurt this stuff at all or direct sunlight in south mississippi.. good stuff pick this up and make them systems thud instead of rattle!!! You wont regret it!! I didn't!!

Delivers a quieter ride

This works very well to put down road noise. The difference was immediate in my van. I was shocked it made such a difference.

Reasonably priced sound deadening

Size: 18 sqft

Easy to cut with a carpet knife. I used a heatgun to make it stickier and more moldable. The foil isn't so thick that you risk cutting yourself like some Dynamat variants.
