I have a 1996 chevy beretta(which I love so don't hate) and I am have seriouse vibrating problems and I was wondering if there is any thing I can do other than hushmat or what ever to keep my trunk from vibrating and what type of "mat" works the best and has any one ever run two type's off of a 125 amp alternator if so how's it working out? Thanks for the advice its been saving me hella money so keep the good info comming thanks
