most of them can do 1 ohm with the right electrical =)
I remember reading a thread somewhere with testings on wattages at one ohm on the 2500.1 and from what I remember it loses efficiency at 1 ohm. so i can only imagine that that amp would do the same as well.
if the amp's specs doesnt say its not stable at 1 ohm then its not a good idea. even the kicker zr amps which were stable at 1ohm produce more power @ 2 ohms then @1ohm. if you dont care about the amp and possibly want to get more output for a few moments then go ahead. most times the amp wont live too long in doing so. but you dont always get more power. more distortion for sure though.
