Right yeah i get you. Right I believe Kris is asking you which amp it is because a dual coil sub should be wired at 2ohm's. You should connect the 2 positives on the sub together and the negatives together and then just one set of connections to the amp of which you could bridge onto 2 of the channels of the amp and then you can use the other 2 channels for the speakers up front.
But need to know more about amp first.
