Just to let you guys know. This amp will pretty much blow any class d 3k amp out of the water.
A local friend and competitor used to run 4 of these.
They are rated 2000w@4ohms mono. they were clamped at 3010.

US AMPS USA2000X
The USA2000X by US Amps is the odd-amp-out in a couple of respects. First off, this was the only one in the test to use class A/B topology. Under normal conditions when an amplifier is not being pushed to extremes, class A/B amps are not nearly efficient as class D or T. However, SPL competitions present a different situation. As these monsters are often played into a serious clip, the efficiency of a class A/B amplifier can measure closer to that of a class D or T.
The USA2000X also is the only 4-ohm stable amplifier of the group. However, this did nothing to deter the beast from producing impressive numbers. Our in-lab results showed it to be quite powerful, making 1685 watts with 12.5 volts, and a more impressive 2100 watts with the juice increased to 14.4. This placed it third in both categories. But placing the USA2000X on a reactive load drastically changed things. Here it took top honors with a very impressive 3010 watts. This is largely due to the 4-ohm impedance design (as opposed to the 2-ohms in the other amplifiers in this test). Therefore, the USA2000X should make more power at the test frequency of 50Hz where the impedance of the speaker rose to 5.3 ohms. In many ways it is fair to say that US Amps had an unfair advantage in our test since the output would likely be higher at this impedance.

The ones my guy had produced 3082w@4ohms mono clamped at 14.2v. At the most pressed load it drew about 350a of current. When overdriven to moderate to heavy clip it produced about 3200w.
And this is all at 4ohms!!!
