That is a great price, provided it works. Even at 4 ohms stereo you should expect MORE than 100 watts per channel. I measured a HCCA 225 to produce 73.5 watts RMS per channel just prior to clipping into a 4 ohm load with 14.4 volts of input. I also measured a HCCA 225 G4 to produce just over 100 watts per channel into a 4 ohm load with 14.4 volts of input.
My only word of warning is that beast is inefficient and loves to draw LOTS of current!
