-> continuous output power.  Burst energy was measured MUCH higher, at -> 
12,000 watts total output power.  In bridged mode, this amp is pure -> lethal 
because it supplies 100 amperes with a 50 percent reduction in -> damping 
factor at 167 volts.  I can ARC weld with this amp in bridged -> mode without 
clipping and a bit of heat off the heatsinks in the amp.
 DH> WOW!!!  Now that is one he|| of an amp!!!  4,000 watts is an awful lot.
 DH> What the heck do you have this hooked up to? 4 18"s?
Those are all sort of "Oh, wow" numbers, just as Sears and Caldor sell 4 HP 
vacuum cleaners (none of which consume enough power to run a 1 HP motor).  No 
load speed/voltage times just short of self destruct torque/current, and you 
have an instantaneous peak extreme.  
As solid state audio amps, Crown's 10,000 watt models are the largest of 
which I know in commercial production.  Those use 3 phase power, and have a 
rated output Z of 0.67 ohm.  In an extreme case, you might use 12 of them 
(120 KW total) as quad symmetrical pairs on the X, Y, & Z axis of an 
industrial shaker table designed to reveal vibration problems in a car or 
piece of mil hardware.  In theory you could use them to drive 8 @ 8 ohm 1200 
W woofers, but it's better to use 4 smaller amps with more flexible power 
needs and better damping factor.  
The larger Stewart amp is about the biggest for which I see a practical need 
in pro audio.  At 17 lbs. and 2 rack units, one can power two double 18 bins 
and 4 double 15 plus mid & high wedges with a single rack two men moving the 
bins would find easy to lift.  (5 amps, 2 on 18's, 2 on 15's, one in stereo 
mode for mids and highs, under 150 lb. rack with crossover and AC 
distribution)  That allows a choice of using a temporary 60 or better amp 240 
single phase drop, or scarfing up 4 120 circuits per rack, for an 18,000 watt 
four way system.  
Of course such amps have some peak headroom too, but that's not what sustains 
solid audio outside someone's bedroom.  Besides, with a 10,000 W amp, 2 AWG 
welding cable would be inadequate for speaker wire.  
Now for a really big audio amp, look at the modulator section of a high level 
modulated shortwave transmitter sometime.  Those can exceed 500,000 KW audio 
output for a 1 MW TX.  (Let's just hook these 300 8 ohm speakers in 
series....)
