ultra linear ul600hc

I have a friend that has a Ultra Linear UL600HC that supposed to put out 3000watts,but I can'nt find no decent spec's on the amp but these                     2 x 300W RMS @ 4 Ohm Stereo

2 x 500W RMS @ 2 Ohm Stereo2 x 1000W RMS @ 1 Ohm Stereo2 x 1200W RMS @ 0.5 Ohm Stereo1 x 3000W MAX @ 1 Ohm Bridged                 I find it hard to believe that this amp puts out even close to 3000watts it has a Unregulated  Power Supply and it is a A/B design and most A/B desighn amps are about 40% to 45% efficient ,some of the better one go up to around 60%.I could'nt even find what fuse size it takes.This may be a great amp ,I just have never heard of it.He had it hooked up to two Solo Baric L5 12'' dual 4 ohms bridged at one ohm .When I got in the car I was excepting it to rattle me to pieces,but I can say I was dissapointed.My two T110D2 hooked up to my RF-XC7 hit harder and sounded a lot cleaner.Maybe someone else that has this amp had better luck,all I can say if that was 3000watts it was a poor 300watts.
