do you have the model number and specs? he can say anything to sell it. If the Orion amp (products range from good to excellent (old school stuff)) is 1 ohm stable and produces 800-1200 watts at that load (or at 4ohms as that's the other wiring option for your subs), then you're good to go. That would be the "right" amp for your subs.
