Powering WS Pro 60's

I am thinking about buying (2) pair of the WS Pro 60's for my new SAN 230. My question is what amp to use. Here are my choices along with the power into each speaker. I currently have the Audison in my possesion and my preference is to us this but am not sure it has enough power. The others I would have to buy and sell the Audison.

Audison LRX 2.4 (115 per) running into 2 ohm load
WS SYN 2 (175 per) running into 2 ohm load
WS SYN 4 (125 per)
JL HDM 600.4 (150 per)

I will be running another JL HDM 600.4 for my (3) paris of JL inboat speakers, a JL 750.1MHD on (2) JL 10W6's in a ported box.

THe boat comes stock with a Polk 10" free air sub behind the driver. I hate to waste this space and am thinking about putting in a JL 10" infinate baffle sub and run in off the WS SYN Micro. Is this a waste. Should I just put a fake cover on this spot and forget it?

I am also planning on buying the WS 420 to control everything.

Any thoughts would be greatly appreciated.
