OK, I think I solved the problem. It seems the remote gain knob was
somehow attenuating the output. I simply unplugged the knob's cord from
the amp and reset the gain. Now everything seems much better and I don't
need 12 decibels of boost.

Thanks for your help, guys. Much appreciated.

Well, when you used the voltmeter and measured 600W at the amp's
outputs, did it SOUND like six hundred watts going into a pair of
twelves? If not, you may have been using the meter incorrectly, or
there could be a phasing problem with your subs. Are you sure the
impedance of your subs at 50 Hz is 2 oms? If it's not, that could
throw your meter readings off significantly.
