inpep: You are using the formula A = (square root of) W/R.
I am using the formula A = W/V. There is also another formula (ohm's law), A = V/R.
They should all yield the same result, so perhaps we're just plugging in the wrong numbers? Additionally, there are some cofactors when using AC, although I'm pretty sure the output of an amp has no phase angle.
There's a neat formula wheel at:
