I may be wrong, but I think you can calculate it by:
Watts = Volts x Amps
So:
Amps = Watts / Volts
Thus, if you're running them on a 240 volt circuit, it resolves to:
A = 200 / 240 = 0.83 Amps
figure out how many amps are in a watt and x by 40

An 8000 watt generator at regular house current 110v will supply 72 amps.

An 8000 watt generator at regular house current 110v will supply 72 amps.
It depends on how many Amps (current) are applied to the voltage. Watt = Volts x Amps. e.g. 12 volts @ 5 amps = 60 watts
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.

A 1450 watt coffee maker will use around 13 amps at 110 volts.
it draws 210 amps
you just need one, a general rule of thumb is that the wattage on your amp should be double the wattegae on your sub, hence if you have a 1200 watt sub you'll need a 2400 watt amp
Multiply the volts by the amps to find the watts.

At 120 volts it will pull 4.166 amps. At 240 volts it will pull 2.08 amps.
