Thanks to Mr Avionic I now have a replacement speaker connection block to install. But still looking at what was installed prior makes me wounder what was up?
As you can see the red (+) were both on the same side and the black (-) on the other. But the common ran down the middle two on the inside tying the positive on one channel to ground!
Ohm'd the to wires on the right and they are common to chassis. But three are grey ? Anyone know for sure how this should be wired up?
