    Icon32 Setting gain with digital multimeter

    Hey i heard you could use a digital multimeter ans put it in the speakers terminals on the amp and play a 50hz testtone and set the gain until the digital multimeter reads a certain voltage around like 36. Is this correct? I have a profile ap1000m and 2 infinity 1230w's getting 250watts rms each.

    Re: Setting gain with digital multimeter

    would it be sqrt(500*2) since 500 watts rms x 2 subs? then that would equal 31.6?

    Re: Setting gain with digital multimeter

    Yes it's sqrt(500x2). But the 2 stands for 2 ohm, not 2 subs.

    Sqrt(Power*Resistance) = Voltage
