Few amp questions

Anyone know how much the Ti600.2 by phoenix gold will push at 2 ohms, their website states it goes down to 1 ohm stable, but won't state the stats, but 600 watts by 2channels @ 2ohms is plenty for me.
What can you guys say about Coustic amps? JBL amps?
Also, how do you use/ mount a mount amplifier?
