At what load?
800w into 4 ohms is 14.14A.
800w into 2 ohms is 20A.
That's at the speaker terminals and only if the amp is acutally putting out 800w continuously. Most likely, the amp will not deliver 400Wx2 at say 20Hz, but maybe 50-60Hz.
If you want to know how much current you are actually putting to your driver with your class D amp, measure the voltage (AC) at the speaker terminal with a sine wave being played through it. Maybe 20Hz or 40Hz. (V^2)/R = current.
