Hey all, tried searching for this answer but i really couldn't seem to find anything that was 100%

i have to rewire my stock 84' f350's radio (the cassette dual **** one model E4AF-19A198-AA) and my issue is, the replacement harness connectors i purchased have grounds for each speaker, while the radio only has 1 ground for all of them, which grounds to the chassis, the following wires are coming from the radio its self (not including the dimmer/ignition wires..i got those :P)

white/green = right front
orange/green = left ront
pink/green = left rear
pink/blue = right rear
black = ground speakers

so since i only have two door speakers, that means i only need to use white/green and orange/green, right? and if so, what the heck do i do with the negatives? do i twist two of them onto a single ground? this is both sides as well. the replacement harness radio side and truck side. Which basically, coming from the radio, i would have two grounds in the harness connected to the black ground wire. coming from the truck i would have two grounds twisted to the single chassis ground, and so when they connect it would complete the connection. to me, this sounds fine but i dont know a whole lot about wiring and i dont wanna blow up this radio

i'll try to simplify my question if it seems too confusing, basically i have to ground two speakers on one ground wire. can you do this without blowing something up or shorting something out?

thanks in advance as always!

 

You answered your own question that is how it works I recently wired in an aftermarket and attempted to use stock took me a minute to figure it out but what you stated is how it works and as long as you have the right size fuse it should pop if something is wrong

 

Hook the Front and Rear wires together. Left Front and Left Rear together then Right Rear and Right Front for proper impedence if you are using factory speakers.
