In older steros from the 70's and 80's, some of the lesser expensive
models did ground all the speakers and voltage together.
Some hade the red wire forkeyed voltage, then 3 other wires. two were
positive left and right, the balance was ground for both speakers and teh
radio itself, usually black.
Had a few of these in hight school as hand-me-downs from people upgrading
or cleaning out their garage.
Hopes this sheds some light.
