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.
