I read on-line that the 04 S4 and 05 Quattro's have Audi's newer second edition Symphony System. Compared to an 04 that I listed too, I have to agree. It really sounds great. It has a sub. Blows the Bose crap away.

The only problem is they took away the hidden EQ, unless someone knows how to access on the new system.

It's an in-dash 6 changer with SAT option.

My O4 A4 had the Symphony II with a in dash 6 disc changer and a stock sub on the rear deck.

 

Oh man, i think ill sell my car for that.
