This is how I generally set them for Rockford amps.

One of the channels is giving me a hard time to set.I set the other 3 ch @0.2mv but the next ch bias starts at 4.3mv and up.I change the port but no change.
Also the 2/4 ch input switch in making the amp draw more current when it is in the 2 ch position.where does this switch have to be when setting the bias?
I have a 50w light bulb for limmiter

My meter shows mv only when it is set to auto range 0.0mv
With the bias port set fully counter clock wise.
Input switch set to 2ch and gain port full counter clock wise.
With emitter and collector short i get .0mv across emitter resistor
If i turn the gain port all the way up at full i get 13.5mv (unstable) across the emitter resistor.
If i set the input to 4ch i get .0mv even if i turn the gain port all the way to full
I think the input section have a problem
