    First, you need to find out how many volts your headunit outputs.

    Second, match your amp gain to that.

    If voltage isn't marked on your amp, how would you do that?

    There is no easier way I don't have all those tools. I thought it would be easy as. If my amp out outs 50 RMS and speakers are set to 80 RMS then I would set the gain to 70 on the amp

    Does your gain have numbers by it?

    Well your amp has a .2-4v input sensitivity.. so if you ratio that out, it should be barely below half gain i believe.

    Assuming you have a 2 volt preout from your HU.
