    The subs have to be wired to amp and the RCA of the head unit go to the amp. The sound is then pushed by the amp. Power and ground wires have to be sufficient in size to handle the load. The power is to be fused with the proper load rating to prevent circuit overload to cause a fire. The remote wire has to be tied to +12V source with switch or spliced with remote wire of the head unit.

    There is an "audio" setting in the IVA-D310 menus for the subwoofer output. It can be set to "OFF","0", or "180" (phase). The setting procedure is on page 44 of the manual. If you do not have the manual, you can download it here:
