    • Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
    • Number Of Channels: 1
    • Bass Boost: Variable (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)

MB Quart NA4-400.1 Nautic compact 400 watt mono powersports subwoofer amplifier with waterproof potted internals and quick release connectors. Features: Compatible Vehicle Fitment Universal Low Noise Preamplifier Circuit The highly engineered Q-Stasis pre-amplifier stage reduces incoming noise from source units dramatically improving sound quality. RCA Inputs 1 pair high temperature impact resistant nickel-plated RCA inputs that allow for secure connections and are corrosion resistant. Operation Mode Mono operation Crossover Type Dial LPF: Complete control of amplifier signal, essential when using two or more amplifiers. Class / Topology Full Range Class D: Highly efficient circuit topology which helps the amplifer develop a lot of power in a very small heatsink. Output Device Technology PWM MOSFET Power Supply: Stable power through the PC board with minimal heat generation. Heat Sink Aluminum: Quickly dissapates heat to allow the amplifer to run lower impedance for longer duration. Power Supply Simpatico Coil Design: The dual coil Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices. Bass Remote Included Included: Wired Bass Remote allows adjustments to gain level to be made from the control mounted anywhere in the vehicle.
