Ok...Looking to put an Alpine touch screen/cd player in my dash. I went to a couple places...NO, not Best Buy or Circuit City, where I thought I could get some honest answers.

Well, at least on of the places is lying or they are just stupid. I have BOSE, so I know that makes a difference, and one guy said I would have to rewire all my speakers.

Another said there is an adapter I can use, but I was quoted $200.

WHO is right? But don't BOSE speakers run at 1ohm and normal speakers run at 4ohm. Does the adapter fix this too?
What have you guys done?? Anybody try putting a shallow mount aftermarket sub in the stock location??
