your gonna want to run it in series mode. havin dual voice coils, your gonna run positive to positive and negative to negative on the one sub which will make that sub 2 ohms, then youll take a positive off that and a negative off that to run to the amp. do the exact same thing to the other sub of course,and once the subs are wired to 2 ohms, when you combine them at the amp, it will make 1 ohm at the amp, which is where youll wanna be. good luck bro-------Rob
