Check out my small build log. I have a 94 Caprice and I deadened my doors. My midbass response is incredible from my Pioneer Premier TS-C720PRS components. I deadened the entire inside of the door and most of the door frame as well. I used the deadener to go over the holes. My panels don't rattle too badly. Change your panel retainers if you haven't put new ones in.
