JL Audio SA-600w subwoofer amp for non-JL audio subs?

I have a MASSIVE pair of subs made by Destination Audio and looking for a good amp to power them. Right now I a Crown XPS and it's ok.  I saw this JL subwoofer amp but also read that's its made for their in-wall sub series. Does that really mean anything?  I love that this amp has JL's room calibration built in.

Thoughts?
