    Set my gains with no subs?

    I was just wondering since I dont get my subs until next week if I could just set the gains on the amp without them. I think I could since you need to disconnect them either way when your setting the gain on the amplifier. Correct me if im wrong.

    Of Course you can! I do it. and i find it more safe to set gains with both speaker wires disconnected from the amp.

    The only thing you can't determine without subs is the actual impedance in-box.

    gains should always be set without the speaker cables plugged, just to be careful.

    Sqrt(Power*Resistance) = Voltage

    power=rms
    resistance= ohm level of speakers

    You will need a Digital MultiMeter (DMM), or some other form of AC Voltmeter. Measure AC volts.
