    Typical overblown wattage ratings. I don't trust them based on this alone. Realize that 2000 watts is more than your toaster oven. At the usual 50% efficiency of electronics, it would consume 4000 watts, more than any circuit in your house could handle.
    Free advice: Avoid this crap.

    Really? You don't think a power supply that is 2.5 inch thick can produce 2000W?

    1) Class D amps, this being one, are usually closer to 90% efficient, maybe a little less to arrive at the low cost.

    2) It's a 2U rack design, 3.5" tall with two fans. They only need to be as tall as the switching transformer, 2000W is possible in 3.5" but that's still a fake "peak" output figure.

    3) Technical Pro's site lists the following which is also believable for a $100 class D amp because they don't claim a low THD figure to arrive at that.

    RMS Power Rating:

    600 watts @ 2 ohms
    460 watts @ 4 ohms
    240 watts @ 8 ohms

    The only picture of the back I could find was too low a res. to be sure but it looked like it has a 4A input fuse so the real maximum possible RMS looks like it's a bit under (4*110V*90%=) 396W.

    ... so yeah it's not a 2000W amp, but probably worth $100.
