The preouts from any amp are a thoroughput. They put out EXACTLY what is coming in on the 2 sets of input RCA's. You would have to adjust your crossover on your sub amp (low-pass filter on).
One option you do have that we have done before is install a decent active crossover. Like the selections from Kicker for only about $70-they have only front and rear RCA inputs-but they convert to three sets of outputs-front, rear, and subwoofer. These actually make a great companion to head units that only have to outputs. But I have found that if you listen to many genres of music, it is best to have a sub amp remote bass knob up front sense you will not be able to control the sub from the HU (only the crossover).
I will PM you pricing on the P4000DVD if you really want it still...
