You can find the amplifier pinouts on Bill's web space writeup on his subwoofer installation http://www.billswebspace.com/A18%20Amplifier.htm

I have the same top hi fi system in my wifes 3.0i Roadster and it rocks compared to my M Coupe.. The only difference is the M has Nav.. The system has sounded awful since I had the car (2 weeks).. At first I thought that it may just be a rattling issue or blown rear speakers.. I checked all subs by removing them and switching them out with the roadster... Roadster still rocks while Coupe is still sucking...... So the subs are fine... I then unhooked both subs in the Coupe and noticed that the audio came to life a little with the remaining 8 speakers... Plugging the subs back up makes everything sound bad / weak... So now I am down to the amp, fuses, and wiring.. I have a feeling that the problem is the amp.... Thanks for the link.. It may come in handy later today..
