Power Acoustik D4-1400B Car Amplifier, 1400 W PMPO, 4 Channel, Class AB

MOSFET PWM Power Supply Metal Oxide Semi-conductor Field Effect Transistors with Pulse Width Modulated circuitry make up each DEMON amplifiers power supply. MOSFET transistors increase durability and longevity over bi-polar counterparts... Variable 12dB Crossovers Filter out frequencies that could cause damage to speakers, or that subwoofers can't play via 12dB/octave slope high pass, low pass, & subsonic crossovers. Variable 18dB Bass Boost All DEMON series amplifiers feature an 18dB 45Hz parametric bass boost. Select models offer variable boost level adjustment to match the limitations of your subwoofers.
