Man, threads like this make me soooooooo glad I got out of the car stereo game a long time ago! I wish I had half the coin I blew stuffing the a$$ end of my Rabbit GTI with amps and subs.

Take front speakers out and put some eDead on door outer skin-as far as you can reach through the hole.
Do not forget to cover door panels-they are the real rattlers.
