87 MKIII, I have 2 JL audio 10" with a 500 watt amp. and when the bass hits, everything rattles. The mirrors, rear view mirror, license plate, license plate trim, rear lights and the trunk rattles really bad and im just wondering if all of you that have a system have the same problem. Or if there is anything I can do, I can probably fix the license plate but I want to know if there was anything like some foam tape that will help, last long without deteriorating and not be noticeable. Also the side mirrors sounds like it coming from inside the mirror. My car sounds good coming but once I pass all you hear is rattling.
