The completely re-designed GM-X572 includes a PWM-regulated MOSFET power supply and DMOSFET output circuitry, dishing out 400 Watts (max.) of smooth, efficient power at low distortion. It offers operation at 2-ohm stereo for more power and the flexibility of bridging power into 1, 2, or 3 channels. A built-in selectable crossover makes installs much easier and so does its new, lower-profile chassis. The GM-X572 features a "New Retro" cosmetic-and higher performance-with its aluminum vertical heat sink, and includes screw-type speaker terminals and oversized power/ground terminals.
