I've upgraded my pre-facelift 99 A4 to a double-din Symphony setup and am interested in a set of rear Bose speakers with amp. I'm not 100% sold on going back to three from aftermarket gear but if you have a set please let me know how much you're looking for. My car came with the Concert head unit and six speaker setup (2 rear deck drivers, 2 front door drivers, 2 front door tweeters) in case that makes a difference.

Thanks
