Yes, they’re well-suited to power two subwoofers. To do this, you can either wire them parallel circuit or a series circuit, but it's easier and better to wire a parallel circuit. To run 2 subwoofers from your monoblock in a parallel circuit, your Impedance of Subwoofers will be divided in 2, so if you have a 2 Ohm Monoblock, you'll be able to run 2 x 4 Ohm Subwoofers. To wire in a parallel circuit, you need to connect 2 sets of red wires into the (+) terminals on the amplifier, and one end each of the other red wires should go into a subwoofer (+) terminal. Then, connect two sets of black negative speaker wires into the (-) terminal on the amp, and attach one end of each into the subwoofer (-) terminal each. For a series circuit, instead of dividing the Impedance by 2 you multiply it by two, to match the Impedance of your amp and subwoofers. So, if you have a 2 Ohm Monoblock, you would have to run 2 x 1 Ohm subwoofers. To wire a series circuit, one length of black wire will run from the (-) output terminal in the amplifier to the (-) terminal in the subwoofer. Another speaker wire will connect the 2 subwoofers from (-) to (+). Then run a red wire from the other (=) terminal on the subwoofer to the Mono Amplifier (-) terminal.
