I finally wrote down my ordeal with Best Buy and my unit problems. If you are interested, you can read the whole story at http://www.gregdemetrick.com/empeg_install.html. The page is very dry but covers most of the issues involved. There is a follow-up on the amp return that I need to add.

Again, big Thank Yous go out to the Empeg crew for helping me fix the unit problems, the BBS for helping me understand how car audio works, and to Custom Car Audio for helping me understand how terrible Best Buy's installers really are.
