I installed two amps and upgraded all my speakers to Boston Acoustic Pros 6.5. I kept the factory head unit and removed the old amp in the rear and used the wire harness with a LOC. Install was very easy because everything is in the rear (wires from radio,speakers and battery)

I hope this helps anybody looking for these wires. Be careful the guy at the BMW dealer told me that not all wire colors are the same.

How did you run the power wires from the battery. Please help because i'm about the add amps to my X5 also. You can email me at

Which wires did you use from the head to run to the new amp? I have an amp I'd like to use to power two new speakers, but am not sure which wires to run from the amp (or head unit) to use.
