Is the amp bridgeable? According to the spec's I just read, the woofers are 4 ohm. If the amp is bridgeable and if the 600W spec is in bridged mode, wire them in parallel (+ to + and - to -) to present the 2 ohm load to the amp, for the full rated 600W. Keep in mind that loading an amp at it's minimum impedance rating will make it run hotter, so be sure to have adequate cooling. I connect a computer fan via relay to the amp trigger, so the fan turns on when the amp turns on and blows across the heat sinks. I also have an exhaust fan with filtered air intake because my setup is in the spare tire well of my hatchback. Just an option for less-than-optimal cooling.
