Product Review

Crunch POWERX incorporates full Class A/B technology in amplifiers. With Crunch POWERX we have trimmed away some of the more esoteric features to deliver a great amplifier that sounds like you would expect Crunch to sound. The POWERX line also includes Crunch technology like QTD (Quick Thermal Dispersion) Technology which puts more aluminum on the heatsink than a normal amplifier. QTD assures the amplifiers make huge power while running very cool with nearly undetectable musical distortions.
