Hello fellow audi owner. I have an RE HC15 (predecendant to the SX) in my 2000 audi a6. Sealed in a 1.7cubft box. The audi is VERY sealed. There is a huge difference from when the seats are up and down. Also get ready for PURE rattling from the rear deck. Even worse, I can't figure out how to get the rear deck off to fix it. Even Ultimate Electronics wouldn't get that biatch off. So if yours doesn't rattle. Feel lucky.
