The calculation depends on voltage in one case or resistance in the other. To keep things simple, try this: http://ourworld.compuserve.com/homepages/Bill_Bowden/ohmslaw.htm

Watts = I^2 times R, in your case the speaker impedance, probably 4 ohms. So SQRT(280/4)= 8.36 amps.

Not enough information.

Amps = volts divided by impedance (Ohms)

Watts = voltage squared divided by impedance
