Tried to reply via PM and email, but both seem to be inoperative right now..

Are you talking about rear deck noises with the stereo on or what?

1. try using some small pieces of carpet between the "contact points" on the rear deck (carpeted part) and the metal shelf thing... my biggest problem was those guys rubbing together causing noise with the stereo up.

2. After that, I'd check the bottom side. if you're not using the rear OEM amps, remove them. same with speakers on the back deck. if you're not using them, remove them.

There's a start.. lemme know what happens.

 

Matt, Maybe he should also try some of that foam sealant stuff. I used to use that with cars that rattled after I installed a big system in it, and the results were great. Plus, with the right techniques, it'll go places where you can't normally reach with carpet.
