My trunk rattles and my exhaust rattles. It seems like my trunk is gonna rattle apart from all the rattling. I have a jl 1000/1 and a 15" brahma in a lexus ls430. All the bass seems like its stuck in the trunk because of the way the lexus is built. Will dynamat stop the rattling? I used like two bottles of road kill on the lid, but it didn't seem to help.
