Square that number and divide it by the impedance load of the speakers that will be connected, assuming that it is not bridged.

If it is bridged, divide that number by two, then square it and divide it by the impedance load of the speakers that will be connected.

Google will do the math for you if you ask it to.

(69V * 69V) / 1Ω = 4761W

Is this for your avionixx amp? If so, you should have it set to about 35V, not 69..
