Any TT electrical gurus out there?
Recently I've been having a problem with the Bose Stereo in my '01. When listening to a CD thru the changer, it will often "cutout" and go silent for 2-3 seconds, before resuming sound thru the speakers. The power for the headunit stays on and the CDs are new, so it's not a skip.
The strange thing is that it only does it when I'm apply some type of electrical load to the system. For example, it will cutout at the very moment that I hit the brake (brake lights go on), or if I flick my highbeams, turn on my headlights, etc. It is a reacurring problem that manifests itself about 95% of the time that an electrical load is induced.
How can an electrical load casue a momentary overload? in the system and effect the CD player. I don't believe that it effects the AM/FM portion of the head unit. I also have the Bipes MP3 adaptor installed - don't know if that matters.
Thanks for any insight that any of you may have.

I think the Bipes adapter is the clue... It will auto switch to the MP3 line if there is a signal
on that line. If you get an audio "pop" on that line, my guess is the adapter thinks there is audio on that line, and switches to it. After the 2-3 seconds of no audio, though, it switches back to CD.
Do you have something plugged in to the MP3 player line? If so, try unplugging it and see if the problem goes away. It could be that the DC load change, especially if you are powering the MP3 device on that line, is causing it to "pop" even if off or stopped.
If not, I still think that is the source of the issue, so somehow it needs further investigation. It could even be the "black box" of the adapter itself. It uses the car's DC power to drive it, and maybe it is getting that "pop" internal to the box itself. Could be one of its internal components has degraded to the point that this happens now where it did not before. A well placed capacitor should solve the problem if that is the case, but I don't know where or what size. An e-mail to Bipes "may" get you an answer...
