Looking for efficiency: New Gen MMats or New Gen HCCA for my HCCA 15.2s?

Ok so i was going to do 2 15.2 Orion HCCAs on 2 Orion HCCA D5000s at 1ohm. and noticed that the amp was very inefficient. i am using a brand new 300 amp Iraggi Amputator and a Kinetik HC2400 in the back. So with just running 1 sub off 1 amp, it would still cut out when i cranked it up. i was told my generation Orion amp is very inefficient and needs Gobs of power.

So ive been hunting for another two amps and ive narrowed it down to two.

first: the Newest generation Orion HCCA D25001, which i can get for $850 New or....

Second: The MMats M2000.1D for $650 (2000 Wrms @ 1 ohm) or M3000.1D for $750 (3000 Wrms @ 1 ohm)

So my question is this, which amp is more efficient and how can i tell by just looking at the specs? Which would make a better match to my HCCA 15.2s?

Anyone?

[huh?do-what?]

mmats says 70% efficiency at 1 ohm full power. Orion says 60% at max power. The orion has more audio adjustments on it. Don't know if that matters to you. If I did the mmats, I would get the 3000 watt.
