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 Concert II+ Headunit. Now I wanted to connect some rear midrange and tweeters on the back doors. Firstly I wanted to know if there is wiring there ( do audi put it in?) Secondly how would I do it? 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.
