If they are all rms values, then you'll want to buy an amp that's at or below 350w rms. Buying a higher power amp could blow out the sub. Its going to be incredibly loud at 350w rms. I'm only running 150w rms (total) to my dual 10" Pheonix gold subs in my car, and its louder than I can handle.
There's two sides to every schwartz, he got the up side and I got the down side.
