Profile amps are kind of shady... JBL are better if you just want a cheap subwoofer amp.
http://www.ikesound.com takes a long time to ship, but they have great prices on JBL. Dont expect great reliability out of a JBL, though. I think like, 10% of owners have had problems. But thats still a lot better than Profile.
The only seperates I knwo of that run at 2ohms are the Image dynamics Chamelons... Kodas are 4 ohm.
You can get just the koda mids, but youre cheating yourself out of it by not getting the whole thing. Sandt38 can hook you up with those (He's on CAF)
Personally, Id stick to US Acoustics or Clarion amps
