I need to figure out how much current is being drawn by an amp. The numbers I need to run are 67% efficency, 200w, 2 ohm and 14.4 volts. Anyone :)

200/.67=300/14.4=21A

200 watts out, divided by efficiency equals input power.

Input power, divided by voltage equals current required.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
