Whenever i turn up my system, which consists of 1 JL 12W3 ran by a JL 250/1, i hear nothing but vibrating. I've had my system for 6 months, but the vibrating started recently. I think i have pinpointed one to the power lock and window controls to the left of the driver seat, and the real bad loud one is somewhere on the roof, i cant really find where it is? It isnt like a rattle, cuz the louder i turn my system, the louder all the stuff vibrates? Any hints to fix this? My system is starting to sound like A$$. BTW, i dont want to dynamat, i just want to tighten the SHlT that vibrates.

 

do you have anything in the side-pockets on the doors? i had an ice-scraper and some other things that bugged the h@ll out of me. i have 2 12w3's powered by a 500.1 amp. i removed those items, and no more vibrations

 

You said that it sounded like one of the rattles was coming from the roof. That might be the roof panel itself. I used to have that problem myself, and the only solution I know of is dampening. If you don't want to dish out the big bucks for dynamat check out rammat.
