Rear Speaker Polarity
The person who installed the AutoCom unit on my bike did a very professional job--he (or she) just messed up the wiring so that I only got mono (sound, that is) through the headsets.
After several weeks of hemming, hawing and building up my courage, and thanks to the invaluable help of the members of this board, I opened things up yesterday and disconnected the intercom add-ins in preperation of doing it right. (I also discovered the problem: the installer did a shortcut and only tied in three wires instead of four, making something common that BMW had decided should be separate.)
As part of doing it right, I would like to make sure I wire the headsets in phase. I've discovered that the yellow wires go to the left speaker and the blue ones go to the right, but if anyone can save me the trouble of opening the top box up to get to the speaker terminals, I would appreciate it.
All I need to know is which wire (plain or striped) is the + and - speaker terminal. Anyone with a wiring diagram or experience who can tell me this?
