Bestselling Mb Quart Na2-400.1, Nautic Mono Block Compact Powersports Subwoofer Amplifier -400 Watts Apparel [6NEnLSWv]

Marine Grade Protection / IPX Rating    
Amplifiers are ASTM certified which defines that marine amplifiers must use conformal coated PC boards to resist corrosion from salt spray & moisture. IPX5

Low Noise Preamplifier Circuit    
Q-Stasis Pre Amplifier Stage: The highly engineered Q-Stasis pre-amplifier stage reduces incoming noise from source units dramatically improving sound quality.

RCA Inputs    
2 Pair RCA Nickel-Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant.

Operation Mode    
Mono operation: Designed to power 1 subwoofer or subwoofer system.

Crossover Type    
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 Dissconect Wires, RCA Connections: Quickly remove amplifer when you are putting machine up for the winter of as a security precaution.

Connection Type    
Nickel-plated connections: Nickel plated corrosion resistant connections.

LED System Protection Circuitry Diagnostics    
Three-stage protection circuits: Monitor thermal, overload, DC, and speaker short protection with lighted indicators on the amplifier end panel.
