Hi i got a 08 528xi with idrive/navi and such.
I was told the idrive provides the power to my door speakers and to the rear deck speakers.

I want to add a 4ch amp and use speaker level inputs to power these speakers instead.
Does anyone have a pin out of the idrive unit to get the speaker signal from.

By the way i have the 10speaker hifi system (s676a)

 

just researched this, and decided not to upgrade. I contacted music car nw and technic (forum user) and both were very helpful with this system.

 

may i ask why not?

 

i will make a custom harness myself to power the door and deck speakers. Using this
