What is it that you're trying to accomplish? You can have the most powerful amp in the world but without adequate power, it'll only distort and sound like crap.
Yes they would work. so long as you have the electrical upgrades to handle what the orions will draw(current wise). Make sure your v.c. configuration is correct for the amps ohm stabality.
Are you going for pure spl? What vehicle are you putting this in? what is budget for amps, subs, enclosure? Do you have or are you planning on getting the needed electrical upgrades to run that kind of power? That could run about $1500 +
