I'm t/s ing the amp/rear door speakers not working but my chiltons book does
not detail circuits .
I expect the amp to be powered when the radio is turned on but it would help
to have a diagram to trace the power source.
I will share a virtual scotch with the provider of a scanned/emailed diagram
nozel99 at hotmail dot com .
The radio is an aftermarket Panasonic CD player connected to truck using a
supplied connector specific to the Suburban harness with the front and rear
speakers working as they should.
The closest info I have found is a generic GM radio connection with a
pink(ant) wire at terminal 8 of the power connector.
There is no pink wire at the amp conector under the driver seat which begs
Is the amp poweed via relay'd circuits?
