i recently installed my 2 12" subs and after a few weeks of "using them", my rear deck and plastic 6x9 bose speaker/amp brackets rattle as i drive. might as well have a 4th gen Would a strip of foam around the brackets suffice or do any of you recommend material like dynamat for the rear deck?

 

I recommend Dynomat, or something similar and also filling the various pillars that are empy and air filled in our cars with expanding dynomat foam for sound deadining considering I have had 2 noise violations I can be first to attest to the problem of it coming out of the trunk and rattling a tiny bit, however we are by no means as bad as a Neon, Civic, or some other cars
