Creating a new thread as this is a very specific issue which I can't seem to find exact examples of online, but am sure others have experienced. My speakers have been cutting in and out lately so I diagnosed today. Checked all fuses, ohms on the speakers, voltage for the speaker wire when Acc power is on. I finally narrowed it down to a faulty/loose connection of the speaker wires on the backside of the stereo head unit. There are two inputs on the back, one for left speaker, the other for right. If I jiggle them it cuts in and out, hence why bumps in the road would make my stereo go out.

Any way to repair the female input on the head unit? Possibly something I could resolder, or even replace the connector? Its an 88 FC vert for reference

Any help would be great, Im no electrical expert Talking

 

try re-soldering them, it will either work or it won't

 

I think that's what I'll do, disassemble and resolder. I mean, it doesn't work as is, so how much worse can I make it
