[s-cars] Schematics for Bose speaker/amplifiers

[Rich Assarabowski]

These are typical sounds of bad units.  The electrolytic capacitors are
known to go bad on these, not sure if they take out other components
when they fail.

Does anyone know of a source of schematics for these speaker/amplifier
units?  I have a very competent electronics friend that's willing to fix
them if he had a schematic.

>Mine did the same yesterday after being at the dealer for five days.
High pitched squeal is extremely loud. I switched off >and on again and
a loud pop came from one or both rear speakers, I immediately shut off
and after a brief pause switched
>on again. All was well for a few minutes when the squeal started low,
increasing rapidly, as if there was serious
>feedback. After switching off and on again it has worked fine since.
Still working today. My front passenger door
>amp/speaker is kaput. Could this have any effect on the rst of the
system? Wondering in Oakville! Tom.
