Does anyone else have this problem? How did you fix it, and what kind of deadening did you use? Weight vs. effectiveness?

The whole back half of my car rattles, even under the car and the rear bumper.

the ride, but I can't get the windows to stop rattling, has anyone swapped out for bulletproofed plastic, or stronger windows short of an SPL looking car.

I would do that too, but my car is setup more for racing then for show.

My deck was rattling like mad, not so much from the bass, but just from going over bumps and stuff it would make a clunking sound. It was the rear deck cover crashing into the metal frame underneath. So I went to the local mullet mart (also known as WalMart), in the crafts department they sell polyfill for making stuffed animals and stuff like that. They also sell it in sheet form, I think it's for making blankets. I paid like $6 bucks for a whole package of it. I cut a piece the same shape as the rear deck and lifted the deck up and laid the polyfill underneath... then snapped the deck back down in place and voila, the rattling and clunking is gone. Best thing is, the stuff is weightless. Oh.. don't forget to cut out the holes for your rear speakers!
