A while back I installed an aftermarket sound system in my 96 GTS. This is the problem.....since I now get great bass response when certain bass notes orlow frequncies hit I get a vibration sound. I have the speakers isolated by mounting them with a neoprene ring between them and the mounting surface(doors and rear deck). It sounds like a "buzz". I think I may have a feww broken tack welds some where in the trunk hood or in the area. I really can't pin it down any further than that. Has any one had this problem before and if so how did ya manage to deal with it?
Hey dwight, which sound shop did ya use to get your head unit installed, I may need to purchase some sound dampening material(to try and solve my problem) from them if they have it.
