The amp I'm planning to use will put out either 750W @ 4 ohm or 1150W @ 2 ohm. So that means each SWS will get either 375W or 525W. My first questions is are there any differences other than impedence between the 2 ohm and 4 ohm SWS? My other question is do you think 525W per woofer would pretty much explode them being that they are only rated for 150W? I'm confident they would be able to handle the 375W with no problem since the amp gains would probably be set to minimum anyway. Headroom is great and all but there's gotta be a limit somewhere.

I have run 125W rated subs off 300W before and it was fine. The limiting factor was that the woofer would max out on excursion far before any clipping of the amp was evident. I also ran a 250W sub off 600W and it was the same thing. I'm guessing I would probably be looking at the same issue with the SWS.
It will not matter if it is 2 ohms or 4 ohms, what matters is to not try to push the SWS-8 to reproduce frequencies in a sound level that will exceed their power handling, and because these SWS-8 are going to be crossover'd between 40HZ to 150Hz I can see that blowing them up will be easy with 525W per woofer. You will need to both keep the amp gains to minimum and keep any EQ gains to minimum within those bands to keep these woofers from blowing up.

I think that if that amp is only for the SWS-8 then it is a waste...
