I am looking for the Bose amp and maybe head unit for a 96A4 or really any year. How about any speakers? Any idea of how to get the head unit to say Bose. After all, it is the same unit. Is it re-programmed? I was considering going aftermarket, but one question I had was how to get 4 front speakers on the front channel of an amp and the four rear speakers on the rear channel of an amp while allowing the frequency control on the rear channel to change only the subs, not the rear doors? The Bose amp does this for you. Any ideas without buying a five or six channel amp?

I am going to rip the entire upgraded bose "concert" system out of my 99.5 A4 the beginning of next month...make me an offer..

includes:
head unit
door speakers
sub
power amp
cd changer

Are the subs on the rear deck? I don't need the CD changer. Does that include all 6 speakers + 2 subs on rear deck? Where does the amp mount? Finally, will the "concert" radio fit in place of the Audi "delta" on a 96? If the radio fits and you include all 8 speakers and the amp + plastic plugs for radio and amp (with just a few inches of wire shown), I would offer you $250. What do you think?
