Decent choice there guy...a dual 2ohm sub can be wired to 1ohm or 4ohm...a dual 4ohm sub can be wired to 2ohm or 8ohm.....visual example here....

With the 350 watt rms power handling your most likely gonna wanna find an amp that does this @2ohm...meaning you should go with the Dual4ohm version...now as far as a amp goes i think this will suit you....... http://cgi.ebay.com/CRUNCH-PZi1000-1-CLASS...id=p4999.c0.m14
Decent price and does rated..got the 1500 watt version for the wife and it's reliable....if you get the dual 4 version you can wire it to 2ohms and get 500 watt rms(which will give you a little headroom) just set your gains properly...any more questions just let me know!
