[QUOTE="i2ain2thunder, post: 8088481, member: 631331"] the equation works like this example: channel on amp u want to produce 700watts rms speaker(s) are wired to the amp at lets say 2 ohms whatever you are going to have for an impedance on that channel multiply channel rms by ohm load, so 700x2=1400 square root that number sqrt (1400)=37.416 now plug dmm into channel on amp, check ac voltage. turn gain on amp to 0 turn head unit volume to whatever u want the max to be, typically choose around 70% volume or so to avoid clipping signal on head unit. then turn gain on amp up untill your dmm reads 37.416 Whatever your HU is volumed at is now your max volume, whatever your amp gain is at is now your max gain.
