Amp not making much power

[Obscenelegacy 0]

I finished installation of my new enclosure and subs.  Everything sounds great.  Went from 6 low end 12s to 2 warden v2 15s 2 ohm. These are being ran by an Orion 5000dsplx. I have them running parallel down to .5 ohms. Actual ohm reading is .9 . My friend hooked it up to his term lab and I'm only getting 430 watts at 3.1 ohms after impedance rise. This amp made 2.8k with my last subs at 2.6 ohms. The subs are loud and sound great with this power but will not make more than the 430 watts.

Batteries are at 14.7

Ohms .9 testing. rise 3.1

The only thing I can think is maybe one of the coils is unhooked. I'm going to pull the speakers out tonight and check the readings.
