The GM-X562. Like a Doberman on steroids, this 2-channel amplifier will behave itself- until you let it go. It features Pioneer's PWM regulated MOSFET power supply, which efficiently delivers 300 Watts (peak) of power at low distortion. To maintain a pure signal, the screw-type power/ground terminals are oversized, and the speaker terminals are screw-type as well. We've added speaker level inputs to give you added control. Plus, a built-in selectable crossover means you spend less time on the install- and more time with your new Doberman, er, your new amp.
