I have an '03 Dodge Stratus SXT Sedan, and just bought a new system for it. After getting it installed, the bass makes a horrible rattle in the rear speaker deck.I want to get in there to lay some dynamat and tighten down the speakers, but I'll be damned ifI can find a way to get underneath the carpet. Those black carpet fastners are everywhere, and I was told to push them out from behind. The only problem being, the entire trunk ceiling and floor is carpeted and have those black screw-like fastners, and I can't get behind a single one to push it out. Is there an entry point I don't know about? Should I just snap them all off and hopeI can get some replacements? Any help on this would be great.

Thanks guys -
KM
