With the impedence rise you will probably get close to a 3 ohm load which would be good for that ampTest done by a teamate of mine:
Tested on 3 Kicker CVR 12's Dual 4's, all paralled to .667ohms.
Nominal Impedence: 0.667ohms
Reactive Impedence: 1.64 ohms
Output Voltage from Amp: 41AC volts
Output Current from Amp: 25AC amps
Power Output(P=VI): 1025 watts
Current Draw: 84DCA
Voltage on burp: 12.0VDC
Not too bad for an amp rated to be a two ohm amp and playing below its rated impedence. 1000+ out of a 750 watt amp is pretty nice. This amp is 375@4ohm 750@2ohm.
