Wiring Dual Subwoofers HELP!?!?

I purchased 2 p3sd210 subwoofers. Rockford fosgates, dual voice coil 2 ohm subwoofers. I bought a Q-Logic box for my Truck (08 tundra) and I'm wiring it all together. I have a kenwood amp stable @ 2 ohms 900 watts. The Q-Logic box is a sealed box, but the chambers for each sub is not sealed. The problem I'm running into is each side of the box has a terminal, with both a positive and a negative terminal.The subwoofer wiring diagram directly from Rockford Fosgate says to wire the positive to the negative separately on from one voice coil to the other on the same sub for both subs. Then to take the positive leads on one and wire directly to the amp and likewise with all the negative leads on the other end of the subs. Except this leaves me with two terminals not being used...a Positive on one side and a Negative on the other side. Sorry if thats confusing...If you don't understand ask me to clarify and I'll see what I can do. My question is how in the world am I supposed to wire these things to present a 2 ohm load to my Amp using this box? Any and all help is much appreciated.
