HELP Wiring Rear Speakers Hey I'm completely new to this stuff. I've got a 57 plate 1.9 TDI 5DR A3 as my first car. I've noticed it doesn't have rear speakers It has the Chorus Headunit. Yeah I figured it was the basic cheap model which sucks Now I wanted to connect some rear midrange and tweeters on the back doors. Firstly I wanted to know if there is wiring there ( did audi put it in?) Secondly how would I do it? Could I add rear bose sub and speakers cheap from ebay OR could I buy a whole bose set and replace all speakers? I want to also add a iPod Kit for it but not sure what is good and compatible since I don't want to pay Audi £££ for a 30min job. Help Cheers Haider.
