Right ive got an A3 on a 2009 which has the bose system installed but it doesnt have the same quality as my previous A3 on a 2005 which had the bose so i kinda know what im expecting to hear which to me is one of the best factory installed car stereos ive heard obviously a debatable fact now ive read the numerous bose threads but still.it seems to be a problem with the drivers side speaker/speakers because if i chance the balance to all left theres plenty on base up front and if i change it all right it missing some vital base and cant feel the same thump comming form the drivers door speaker but need some one to tell me /have a look and work out if its just the door speaker and or what i need to get it sounding right ie a good audio specialist in the leicestershire/northamptonshire area thanks guys
