First of all - hello! I'm a new member to this group. Just bought a 2011 plate A3 TDI SE. Very, very impressed with feel of vehicle, etc. The Chorus CD/Tuner is a bit woolly and I notice it only powers the front speakers. Firstly, I am considering getting a Symphony II but worried that (a) there won't be the necessary wiring behind the dash and, (b) there aren't any speakers in the back anyway! Is this the best set up? Are there better sets/speakers out there? I see Bose speaker sets going on Ebay for £100-ish but are they overrated? Some of the double-din units in Halfords look good but I don't want to lose my steering wheel controls. Also, I have the iPod dock in the glovebox and would want to retain this... Thanks
