I've got two 1600watt max 12" subs, each 2 ohm DVC. The RMS on the subs is 800watts. I have a 1600watt D Class mono amp. At 4 ohms, RMS is 500 and at 2 ohms, RMS is 900. Should I just be hooking up a single voice coil on each of the subs and running them into the amp (The amp has inputs for two subs). Or, should I hook up both voice coils on each sub and then run them into the amp?
