The super-efficient GM-4000F amplifier dishes out 300 watts of peak music power and can be configured for 2-, 3-, or 4-channel operation. Its pulse width modulation (PWM) circuit efficiently outputs only the lower frequencies, which makes it ideal for powering a sub or two. The selectable high-pass and low-pass filters give you flexibility for your system, and the 4-channel speaker level input offers added control. Oversized screw-type power/ground terminals and RCA in/outputs are provided.
