There are no stupid questions, just stupid people that ask questions.
You need a mono sub amp that will run a minimum of 1-2 ohm mono load. Then wire you subs in parallel, not series, to present a 2 ohm load to the amp. Do not do this with a 2 channel amp. First, the load presented is different for stereo amps wired in mono. Second, stereo amps are normally class a/b. You want efficient as possible class d mono sub amp.
For those subs, I'd go with a 300-500w mono amp.
Yeah What he said!!!
