Main Question or Discussion Point

I have a 38 watt amp and I'm trying to figure the Power it produces, but I'm not sure how to find the Velocity. Can anyone clue me in on this?
And I know to use the P=V^2/R

And sorry if this is in the wrong forum, I'm new.

Thanks

EDIT: I just found V=f/Lw (velocity=frequency/wavelength) but how do I find the frequency and wavelength?

Go back to the source of your first equation:

[tex] P = \frac {V^2} R [/tex]

Find the meaning of each symbol, I'll bet that V is NOT velocity.
