E70 audio wiring

[cprx7]

I sold my e70 it had a full aftermarket system. I took me a while of searching to find this information. I no longer needed it, so in case someone else needs it, here it is. This is for 2011 X5 E70 50i.

This is from the plugs going into the factory amplifier located in passenger side trunk compartment. The pins are numbered on the plug shells. In case your wires are different colors, you can always go by the pin location instead.

Thicker wires are the outputs to the speakers:

Center channel:
Pin 40 - Black/Brown = Negative
Pin 39 - Black/White = Positive

Front Left:
Pin 34 - Blue/Brown = Negative
Pin 33 - Blue/White = Positive

Front Right:
Pin 12 - Blue/Brown = Negative
Pin 11 - Blue/Black = Positive

Rear Left:
Pin 32 - Yellow/Brown = Negative
Pin 31 - Yellow/Red = Positive

Rear Right:
Pin 21 - Blue/Brown = Negative
Pin 13 - Blue/Green = Positive

Sub Left:
Pin 3 - Brown/Yellow = Negative
Pin 4 - Red/White = Positive

Sub Right:
Pin 22 - Brown/White = Negative
Pin 23 - Red/Blue = Positive

Thinner wires are the inputs (High-Level/Speaker Level):

Front Left:
Pin 30 - White/Black = Negative
Pin 38 - White/Green = Positive

Front Right:
Pin 17 - Gray/Purple = Negative
Pin 9 - Gray/Yellow = Positive

Rear Left:
Pin 29 - White/Yellow = Negative
Pin 37 - White/Blue = Positive

Rear Right:
Pin 16 - Gray/Green = Negative
Pin 8 Gray/White = Positive

Power:

Pin 5 - Red = 12Volts
Pin 26 - Brown = Ground
Pin 10 - Black = Remote Turn On
