C3 stereo radio hook up

[Jeff A.]

Replacing aftermarket radio with an original stereo. It has two geen and one black wire on the speaker hook up. What's the correct hook up to each speaker as the plugs have been cut off the speakers. does it matter which is the common wire on a speaker assuming that the black is common ? Thanks Jeff

Re: C3 stereo radio hook up

Are your speakers original equipment on your 70? Reason I ask is there is something about different OHMS for radio speakers and original radios having the right OHMs speakers.

The black is the NEGATIVE. *NM*
