How many watts will go to each subwoofer?

Im not sure what ohm subs u have. I think you have a type o but i will say if you run at 4 ohms then each sub will get 150 watts each. If you run at 2 ohm then each sub will recieve 300 watts. Basically whatever your amp puts out will be,divided among how ever many subs you have. In your case the amps power would b divided by 2
