Alright, If you have a BMW Professional System, the subwoofer pin outs (for speaker level signals) is:
Left: Pin 4 + Pin 3 -
Right: Pin 23 + Pin 22 -
This is on the amplifier.
I will provide you guys with the connector in one sec.
In terms of the Remote wire, there is no such thing. The amp is activated by a on @ 8 Volts, off @ 6 Volts.. You need to use either a ignition wire (with the use of a remote line delay) or a speaker line remote.
