We have two pv215 which are 700w continuous at 4 ohm. How should we size the power amp for that?

| Most speaker manufacturers have their amp recommendations on their web site. If not, figure out what the peak power of the speaker box is and find an amplifier with a similar output rating. My gut feeling is that an amp with a 2000W @ 4Ω rating per box will work fine. |

The RMS on those are 350W and the peak is 1400W.
I'd get an amp with some built in electronics & a limiter that puts out 700-1000 watts RMS per channel at 4 ohms.
Under no circumstances would I get an amp that has an instantaneous peak power rating less than 1400W.
Here's a nice Crown with built in goodies:

I know what others will say, but this would be a decent rock bottom priced amp for those speakers:
