it's a cheater amp, with a real convenient cross-over built-in to run a mid/high amp out of the cross-over section. the real approximate ratings vs advertised:

Continuous power @ 14.4 V
150 watts rms at 4 ohms
300 watts rms at 2 ohms
375 watts rms at 1 ohm

Continuous power @ 12 V
(IASCA "cheater amp" rating)
50 watts rms at 4 ohms
100 watts rms at 2 ohms
200 watts rms at 1 ohm

< .006%
