Hi, ive just registered on here, I bought an audi A4 avant estate earlier this month.

I promised myself, after a few motors loaded with aftermarket stereo equipment, that i'd leave the new audi bog standard. But after a few weeks of a real lack of bass, ive decided to add a small sub/amp in the back just for a bit of low end fill.

Its already got the harmon/kardon setup, 6 disc changer with a sub/amp in the boot. What im gonna do is use the remote on signal and audio line level cables off the amp for a new amp in the wheel well. then just run a power cable to it.

Does anybody know, or know of anywhere i can find out which of the cables into the connector are the audio signal cables, assuming theres 2 channels (stereo)? also if anybody knows which ones the remote on cable, it would save me testing them too!!!

Any other tips/hints would be greatly appreciated guys!

Joe.
