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 ***. BTW i dont want to dynamat, just tighten the stuff that rattles.
