oh, and the math i used:

Apparent Power = RMS Voltage * RMS Current, AC measuement on output of amplifier.

Power = DC Voltage * DC Current, DC measuremens on +12V input of amp.

this gives the apparent power out (to the speaker) and the power to the amplfier.

efficiency = output power / input power.

Impedance Magnitude = AC Voltage / AC Current

this is the end of the basics. from here you can construct a right triangle with a hypotenuse of 256VA, and another side of 0.95*256VA. using trigonometry, one can solve for the angle (impedance phase) and the unknown side (VAR).

Well the reason I know its not working right is that it is on my 2500D.

I have that same clamp but I got mine for 45 not 20.
