clamped

Hi there. Got my system clamped. JD1000/1 pushing a 12" CompQ DVC4 wired to 2ohms. My JD1000/1 is 1000w rms at 2ohm stable. No stability at one ohm. Clamp reveals 537w at 4.0Xohms. Since this is contingent off of the box, cabin, car, etc, CAN I replace my DVC4 with a DVC2 to wire it to 1ohm...
