[Accord Man]

your amp delivers 600w rms @ 2 ohms..

You got the 2ohm DVC Comp VR right? If so, exchangine it for a 4ohm DVC Comp VR, so that you can wire to yield a 2 ohm load.

Or get another 2ohm DVC Comp VR.. Wire the to yield a final impedance of 2 ohms, and each will receive 300 w rms..

But you sub, can handle a lot of those 600 watts.
