Hello all,
I have a 2015 SL w/ the Bose package. Recently, my drivers side door speaker stopped working suddenly. No static, no paper cone noise, etc. As the corner tweeter was still working, I assumed it was the door speaker itself. I took the door apart today and tried to install a new speaker just to test it out. new speaker didn't work either. I tested the old and new speaker with a multimeter and both were fine. The tweeters and front doors are wired in parallel, so they receive the same signal on their respective sides. I decided to get behind my head unit and swap the left/right channels. Left door speaker still had no sound, and the right side was playing the left channel fine. That takes out the head unit/amp issue. So before I start tearing my dash apart just trying to rewire my left door speaker, can anyone tell me how the Bose system is wired? is it headunit->amp-> speaker? or do they do some stupid proprietary thing where I have to trace the wires from the behind the head unit to wherever it goes so I can cut and splice to rewire it? Also if anyone has had this happen to them before please share.
