I'll add some stuff about teh ///M audio upgrade that i've found. Credit goes to anyone who found info on it.

The details for the connectors are

61.13-1 378 136 This is the 12 pin connector to go to the DSP sub connection. 1 of these.
61.13-1 378 132 This is the 4 pin connector to connect to the M subs. 2 of these.
61.13-1 376 193 This is the part number for the pin (1.0 - 2.5mm2) to fit both housings. 16 of these.

I purchased the subs through www.bmaparts.com, speak to Patrick ONLY. I paid $205 per sub. I have a 9/97 production 540i 6-spd with DSP, and i had to drill my own holes. I must add that this was a huge pain.

Hmmm . . . my notes are not quite as crisp as they seemed at the time:

Based on color coding of the wires, I have the following associations between the drivers and the wires in the connector, including polarity:

Rear left voicecoil 1 + yellow/red - gray/brown
Rear left voicecoil 2 + blue/white - blue/brown
Rear right voicecoil 1 + yellow/white - yellow/brown
Rear right voicecoil 2 + yellow/black - yellow/gray

I also think I use the wiring diagrams at http://www.bmwtips.com/ as reference. The connector my wires go into is a 12 pin connector, with the outside pins unused.

If you look at the attached picture, the following pin pairs each power 1 voicecoil:

5-4 3-2
11-10 9-8

(the subs are each have dual 8 ohm voicecoils)
