Unplug the speaker connector from the back of the
radio and do a resistance check between the two grey
wires (-) for the rear speakers. If you get
continuity, the wiring utilizes a common ground. If
not, you should be able to use the current wiring with
a new headend unit.

FWIW, the wiring for the speakers in my '87 Camper do
not share a common ground.
