Hey All,

I have a am/fm radio is my 68 that I got a new set of dash speakers for. Please excuse my lack of knowledge when it comes to wiring everything up. Seems like it would be simple, because there are 4 colored wires coming from the back of the radio which I assume are speaker wires, a black ground, and the power. if I connect all each of the four wire to the new speaker wires I get nothing. If I attach a wire to the speaker wire, and touch it to the ground, it works. This doesn't seem right to me.

Any insight or guidance would be appreciated.

Thanks

 

What radio?

 

This one.

 

I am not familiar with that radio, but older radios would have a common ground. Does the radio have a fader for four speakers? If so, the wires out of the back are the four positives and the negatives tie together to the black. The radio ground would be a screw in the chassis of the radio to metal. Just a guess..... You can try it this way, it wont burn anything up.

 

Common ground, bro. Two are for front, one ground, one power.
