Hey guys, so I'm trying to hook up my subs and amp in my room using the computer psu method.

These are my subs: http://www.polkaudio.com/products/db1222

And this is my amp: Hifonics BRX2000.1D

My question is how much power does my psu have to have to run my system?
I've attached the amp specs.

    I don't think a computer PS can supply 200 amps of power at 12V, but I could be wrong.

    A Coolermaster 650 Watt power supply would only supply 1/4 of the power that your amp would need at full power. If you were to keep the power levels down, I guess it would work for awhile.

    At full power, your amp will want 2400 watts of power available. 200 amps @ 12 volts.

    1750 watts.
    And yes a plate amp is far more efficient/cheaper.
