4000 Watt 1 Channel Amp with a strong 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 features an 18dB 45Hz parametric bass boost. Variable boost level adjustment to match the limitations of your subwoofers. Remote Gain Control allows amplifier level adjustment from a remote location in the vehicle. Strappable! Get double 1 ohm power on a 2 ohm load by strapping two like DEMON Class D amps together.
