Question about 2006 Audi A3 2.0T
The connector was removed so all I have is the wire bundles coming from the sounds system. The person who wired it did it incorrectly, they wired the RCA outputs to the front/rear door speakers (with ground not hooked up), and and nothing to the amp/sub. It sounds bad and whines with engine rpm and brake application, I think the grounding is screwy. Thanks.
You can't use any of those - the large connector at the OEM speakers is because the rears are amplified. Your factory head unit puts out a line level signal to the rear speakers. There's an amplifier on the driver's side rear speaker (the box around the magnet that you can see from inside the trunk).
You need to either replace the head unit with an aftermarket one to drive your new speakers, or you need to tap into the amp connector and find the line level wires, break them out, put RCA plugs onto them, and plug them into an aftermarket amp, which you'd use to power your rear speakers. Doing it that way allows you to keep the factory head unit.

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"
I had the same problem a while back after having a JVC MP£ player fitted at Halfords. The guy told me my sub-woofer behind the back seat wouldn't work with the new stereo which I said was ridiculous, then one of the other guys came to look and told him I needed a different cable to link everything together - then it worked brilliantly.
Sorry I dont know a part number but that is definately your problem.
I hope this helps - or better still that you already have it sorted !!
