MB Quart NA4-400.1 Nautic compact 400 watt mono powersports subwoofer amplifier with waterproof potted internals and quick release connectors.

General Features:

• Compatible Vehicle Fitment    
  Universal
• Marine Grade Protection / IPX Rating    
  Meets or exceeds IP67 standards for waterproof and dustproof. Potted Internals: The potting material seals the components, insulating them and ensuring better durability, especially in harsh environments where exposure to moisture or water might otherwise cause short circuits, corrosion, or other performance issues.
• 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.
• Output Connections    
  Quick Connection Power Wires and RCA Connections.
• Connection Type    
  Nickel-plated connections: Nickel plated corrosion resistant connections.
• LED System Protection Circuitry Diagnostics    
  Protection circuits: Monitor thermal, overload, DC, and speaker short protection with lighted indicators on the amplifier end panel.
• Bass Remote Included    
  Included: Wired Bass Remote allows adjustments to gain level to be made from the control mounted anywhere in the vehicle.
