Hello,

I took pics to help everyone know what I am talking about here, sorry if its already been discussed before (maybe we can make this a one stop shop for adding an aftermarket amp to a logic7 system.

Ok been researching all day, I didnt even know what my system was called before today or where the stock subwoofers were located (under the seat, cool!). Heres where I need help

Attachment 1 - How do I remove the wiring harness?

Attachment 2 - What are these plugs and what are they for? they almost look like RCA Plugs but I think we have Fiber Optics not RCA

Attachment 3 - Can someone tell me what color wires to splice into for the speaker wires that go to the sub so i can run to my amps high level inputs (or a low level converter)

Attachment 4 - Whats this for?

 

Wow 33 views and not one answer? thanks for pulling together BMW community!

 

The last picture is a bracket for a cd changer. Hey, that's all i know. I'm sure others will chime in now.

 

Attachment #2 : Its fiber optic connector. You need to handle it carefully. I recently installed OEM Ipod Adapter ..It had same fiber optic cable with black sheath to protect.

 

You remove the wiring harness by pressing the tabs and sliding the harness to your right(not up). Attachment two is the fiber optic which is a part of the MOSt Bus if the ring is not complete non of your communication/entertainment will work. The most ring includes the CD changer, Idrive/Mask, Satellite, TCU (bluetooth, and amplifier. I do nt know where to splice the wires. Try doing a search I have seen someone posting about that.
