I have a system in my '97 Prelude (Panasonic head unit, Alpine 300w x 1 amp into 2 12" Kenwood Tornado subs) and the thing rattles my trunk and even my side door panels like hell. I was wondering if porting my box (it's completely sealed right now) would take away some of the rattling from the trunk. I may also just Dynamat the trunk and speakers in the doors. Any suggestions to help stop the rattling? Thanks.
