when the bass is hitting hard it makes my cd skip. on the back of my HU i have the rubber piece on the post which is going into the car's bracket support. i cant fit my hand in there in order to actually bolt the rear of my HU to the bracket. would this actually help, because my *** rumbles with the bass, so i assume the whole car is shaking. if i bolt the HU to the car's bracket, will i have the same problem? there is no dynamamt in my 93 escort, would adding some help, or is my sony HU prone to skipping?
