...enjoys spaghetti.
Hello. Haven't been on AK in many years, having been mostly into vintage TVs, I migrated to VK. At any rate, I'm hoping an audiophile might be able to help me.
I've got a 1979 Dodge Magnum with the OE AM/FM/CB headunit that works fine. However the stock speakers are weak/shot (and it probably never had the volume to compete with removed T-top noise)! I want to keep the OE radio and simply power some better speakers, which means "amplifier".
Problem is, the OE radio uses a single "-" feed that goes to all the speakers through the sheetmetal. I have all new wiring to the new speakers. I want to feed the amp through the high-level inputs for auto-turn on.
Plenty of gadgets and info for keeping the stock wiring to speakers, but I can find nothing for supplying an amp with a vintage headunit.
The diagram shows how I wired it, but all I get is weak sound and a "protect" light that comes on/off.*(There is an error in my drawing, which shows the - pinouts on the outside of each harness. In reality they are on the inside, + is on the outside. The actual wiring does not have this error.)
An ohmmeter shows continuity between each of the two center harness grounds as well as the amp's ground terminal.
The amp is a Dual 4 channel 4x100

I've attached a page from their manual, as well as the OE Mopar wiring diagram (mine is model xs rather than et)
Any ideas how I should do this differently? Thanks
