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!!
