Ever consider MB Quarts? Possibly the premiums or Q-lines... IMO they produce notes and sounds I have never heard before compared to BA's, Inifnity's, Bose, etc. I think RideAC1 will vouch for MB's too!
I looked up the amp, and it's 200rms per side, and the tech specs aren't that great to be running a quality set of components from. I'm on caraudio.com forums too, and just saw your post.
Orion's are decent so that should work though.
I like MBQuarts too, I don't know if you checked into them or not.
