Thanks. PM sent.
I just got done swapping the Kicker CVT for the Rockford P3SD-410. I think I wired it correctly for a 2 ohm load. It's a 4 ohm dual voice coil. I wired both reds to each other and both blacks to each other then to their respective amp connections. That's right, right?
I had to slightly enlarge the hole on the existing box to get the Rockford sub to fit. As it turns out, this box was made from little more than compressed paper. I was able to expand the hole easily with a standard exacto knife. This baby needs a new box.
