having a single voice coil is no different than a duel voice coil. a duel voice coil allows you to have the option of running 2 different resistances. so a 2 ohm DVC can be wired to present a 1 ohm load or a 4 ohm load.Correct me if I'm wrong: the original is a dual voice coil (2 coils, 2 ohm each). The thought is that 2 voice coils produce better base than a single voice coil. Effectively, the 2 coils are pushed by the single factory amp with a total impedance of 1 ohm.
The CVT651 is an SVC (single voice coil) with 1 ohm impedence. If you connect both positive wires (grey red) to the pos terminal and both neg wires (black brown) to the neg terminal, you will be pushing a single voice coil at 1 ohm.
By using a 4 ohm single, you would be reducing the total shown amperage to the speaker by 1/4--about 17 watts vice 75.
That's my understanding: 75 watt factory amp shown 1amp via 2 2 ohm voice coils.
the Kicker cVT651 single voice coil at 1 ohm should be fine.
Others have had reported good results with 2 or 4 ohm units, but most add an aftermarket amp.unk:
