Battery alone 12.5
Battery hooked up 12.45
At amp 10.76
Bike running at battery 14.47
At amp 14.5
Sony mex-gs620bt head unit
I tried to set the gains but i kept gettin 0v no matter what i tried. I hooked up one speaker to make sure i had sound and it worked fine. I tested the volts for the gains with the bike off. It didn't matter how much i adjusted the gains the meter never went over 0

Sounds like you may have a bad connection between the battery and the amp. My first check would be the fuse connections and/or replace the inline fuse.

If the voltage at the amp is only 10.7 vdc that is an issue. You should have the same voltage at the amp DC connections as the battery voltage.

How does the lack of an inline fuse mess with volts at the amp?

Wouldn't the battery voltage I posted above clear the better of any issues?

Bottom line, you should not be seeing more than a .10 volt drop on that connection, it should be nearly the same at the battery end of that cable as the amp end of the cable.
DO NOT rule out a bad ground. If your chassis ground from the battery is ****, you will also get that result on your meter.
