opinions on JBL 600.1

I'm planning on running 2 12w3v2's or 2 12" idq v3's, would a JBL 600.1 be a good match for these subs?  If I run the JL's at 2Ohms it would be 300watts per sub which is the RMS, the idq's have a 250rms, but it should be fine at 300. 

Opinions on the JBL 600.1 quality wise?  Will it have bad sound quality, or will be be just fine?

These amps are MADE for pushing subs and they really do pack a punch.  I like the fact that they can handle really low ohm loads (1 ohm manufacturer recommended, but I've seen them run at lower loads);  it makes wiring up subs a whole lot easier.  From what I have seen they are pretty tough and will last you a good while.

Of course the usual advice applies:  don't push it past its designed limits, give it ample room to breathe, and hook it all up correctly.
