When you get it you should measure the unloaded voltage at clipping, with a 60hz sinewave. You should get +95volts or QSC is lying to you. QSC is not known for lying, but it's always good to double check.
In order to do 2kW x2 or 4kW bridged continuous you'd need a 50amp breaker and corresponding wire gauge on that beast. Otherwise you won't "actually" see that number.
With only a 30amp breaker it is not "realistic" to expect more than 1.5kW x2 continuous (3kW bridged) with even a very efficient amplifier.
With a 20amp, 900watts (1.8kW bridged), and a 15amp 700watts (1.4kW bridged).
Burst can be much higher, but not the continuous for more than 1-10 seconds. The panel breaker ensures it won't happen, as do any internal fuses/breakers.
If you like dubstep at full volume for minutes on end, you'll need a 50amp breaker and a 10kW old-school Class H amp like the Crown MT-10k.
Dual 0.5ohm? No Problem! POWER HAS ARRIVED!
