I bought this amp looking to run two JBL GTI 10 subs bridged. The subs are a dual 6 ohm coil but actually meter out closer to what a single 4 ohm sub would be when run parallel. 3.4 ohms or so. Anyway, I just finished setting my gains with the car running using an SMD-1 and I have some results for those of you interested in this amp.
My car idles at around 13.8 volts for starters, big three uprade. Using a -10db test 40hz test tone I was able to get 698 watts per channel bridged at a 4 ohm load and 978 watts per channel at a 3 ohm load bridged. It seems to handle bridged to 3 ohms no problem. No overheating, sounds good, no complaints. It does a bit under rated power as you can see especially using the 4 ohm resistance load. I would assume at 14.4 volts it will in fact do rated power, but most of us don't have that luxury. Still 2 x 700 watts @ 4 ohms is very very respectable. The only complaint that I really have is out of the box the remote gain did not work. I will be working with hifonics to remedy this.
