um?.... so the gain has nothing to do with the amp? how is that?
I said with the output of the amp. You don't get "more" out of your amp by turning the gain up, you get the most out of your amp by setting the gain correctly, and that correct setting has nothing to do with output, but the input of the amp. The higher the input voltage, the lower your gain is set.
his not talking about battery voltage his talking about the voltage the h/u send through the rca. it can be 1v it can be 2v it can even be 5v so depending on h/u that you will have to set your gains
