99 A6 speaker problems...
 

Hey guys so I just got a 99 A6 Quattro, pretty sure it's the Bose. I'm not getting any sound from the back speakers, and the front are TERRIBLE. I really want to change all the speakers to something like kenwood or kicker, but I'm not too sure how that'll work out with the Bose amp. Could I just buy all kenwood speakers, and a kenwood amp and run it all in the same setup? Or should I go ahead and get all new stock speakers and a new stock amp? also I'll be throwing in 2 10's with its own 1000w amp if that info helps! Any help is greatly appreciated!
