Question about 2005 Audi A3
Rear speakers/sub-woofer intermittently used to cut in and out. Appeared to improve the longer the radio/cd player was left on. Replaced the radio for a Kenwood set, however the wiring appears quite different and I have no rear speakers at all now. Does anyone know the correct colour wires for the rear speakers and which wires power the sub-woofer? I'm a self employed mechanic, but to my shame I'm lost on this one. Many thanks.
Hi, had total issues with this too! Your back speakers arent going because they are amped by the factory amp in the boot. You have to provide power to the amp so that it will turn the rear speakers on. This was a white and black striped wire in my car (Audi A3 1997) The rear speakers are blue /green and brown/red (left rear) , and the LH rear is brown/red and (forgotten colour) but the wire on the bottom left under those two brown/red wires on the 20pin harness. If you wire it all up like this then your rears should be going :)

Testimonial: "So sorry for the very long delay in replying to your advice. It was the sub/amp in the boot as you correctly guessed. Another £200! Many thanks Pal"
