if you wallet permits id suggest the Helix as well 
pretty much a no brainer in terms of power output at 4 ohms bridged.... you gonna use your passives for the comps so you'd get 250 x 2 at 4 ohms... twice the power of the RF amp...
Plus the helix is so much sexier [img]graemlins/thumb.gif[/img]
you even have enough power to probably go active on your setup
