Question about Car Audio & Video
I need to identify speaker wires from hot and ground wires for a 1957 FoMoCo 12 volt radio [ Not installed.] There are two black wires on the left side of the case. One is soldered to a copper plate on the case, which also has a bare copper wire going to a copper coil.. The other goes to separate copper plate on the case, along with a wire to the on-off switch. These both appear to be grounded to the case.
In the back of the case is a fibre plate with two small holes for a plug-wire. The smaller [[green] wire goes to a larger copper coil which also goes to ground.. The larger hole goes to a ground on the case via a black wire.
I appreciate any help as I do not wish to blow anything out.
Thanks, Ray Latimer
There are actually 4 wires on the right side 2 are speaker wires and the other 2 are the positive and negative connections . the black wire is positive supply and the green/red wire is negative earth . strange wiring !!
