So this amp can mke 6,000 watts. and only costs $400. The new "Let's blow up some speakers" King is in town.

Seems like a hump-style, sub-woofer amplifier, to get those cones launched.
wildly exaggerated. Here's why, 3,000 watts per channel at let's say 95% efficiency, because 100% efficiency is impossible to achieve, would draw 52.6 amps of current at 120 volts. And yet, buried in its specifications the Behringer I Nuke draws only 620 watts. So, that's less than 300 real world continuous output watts per channel; granted 300 watts per channel is still powerful enough to fry a few speakers. It is just not anywhere near 3,000 watts output; what were they counting, output power for less than one millisecond duration? As Tim de Paravicini once said, You can't squash a watt.
Let's see how much continuous output power it has for five full minutes at less than 5% THD, without overheating or blowing a fuse. Still, it would probably be fine for subwoofer duties at a very low cost.
care about the continuous sinusoidal power output of an amplifier when the second by second peak to RMS ratio of a music signal rarely - even Wakefield's Synthesizers - drop to less than 13dB. A 13dB power difference is a ratio of 20:1. Yes, in the old days of Hi-Fi (before the IEC specification started being used) peak power ratings were abused - almost as bad as Behringer does here - often arbitrary. But for todays amplifiers, Amplifiers shoul be rated with a crest factor - how much above the rated power voltage into a typical loudspeaker load (not a resistor) will the voltage be able to swing until current is limited - or a certain level of non-linearity is reached.
Three most important things in Audio reproduction: Keep the noise levels low, the power high and the room diffuse.
Lets say I have an unbalanced preamp with RCA outputs and speakers with binding posts. Is it easy to get preamp-amp cables and amp-speaker cables for this amp?
they claim that wattage which is some sort of "max" rating. Pro Sound often avoids the "X watts into Y ohms from 20-20K @Z% distortion" formula which gives a better picture of actual performance. Crown, QSD and Peavey follow this model.
There's a Peavey at Parts Express for $449 that claims 1500WPC @2 ohms and it weighs in at a hefty 7-1/2 pounds. Even at 100% efficiency which is impossible 3000 watts divided by 120V = 25 amps of line potentially current needed yet it has a 15A IEC.......
All of these amps use class D switching supplies. They offer a good value I guess. Crown and QSD also offer a similar unit to the Behringer with the DSP/Crossover/EQ functions.
