I dont see any way of making 2900 watts with only a 200 amp max draw.
The math just doesnt work right. Amps that do put out rated Power like rockford t4000's have a 500 amp fuse.
With a 200 amp max draw and 14.4 volts which a Car will never see under a heavy load like that unless you have a seriously overbuilt electrical you are still only going to get 2880 watts at 14.4 with 100 percent efficiency.
Maybe that amp is 80 percent efficient, that would drop your wattage down to 2304 watts at 14.4 volts. Now drop it down to 12.6 volts which more cars are likely to run and you will see 2016 watts at 80 percent efficiency. Sorry for the long drawn out post but i figured it would help.

Edit:::I know these numbers are not exact since the environment in a car is completely different than a test bench. But this gives an idea of what kind of power it is capable of. Impedance rise is also not factored in.

Disregard what dave said. To make that much power at 14.4 volts it would have to be 100 percent efficient. Yeh they are overrated but they might be goo amps. My powerbass has a 200 amp fuse and is supposedly a 3000 watt amp. But, it will handle voltage drops to 9 volts like a champ so im happy with it anyways.
