Isaac, I don't think he has to worry about wiring in series since the amplifier has 2 speaker outputs internally wired in parallel. If you wire each sub for 4 ohms, the ohm load will be 2 ohms anyways. So there is no need for parallel or series wiring.
Please note that when wiring multiple drivers, whether DVC drivers or their SVC brethren, it is recommended that series connections between drivers be avoided at all costs. This does not include series connections made between voice coils on the same driver. For more information, please consult our DVC FAQ section.
