Nautic Series Marine Class SQ Amplifier (560 Watts Max, 4 Channels)

The MB Quart NA3-560.4 is a 560 watt 4-channel marine amplifier. It is waterproof and dustproof, and has marine-specific connectors. It also features top-mounted sound contouring with onboard crossovers, bass boost, and adjustable input sensitivity all concealed behind top-mounted controls. It also uses SMT (Surface Mount Technology) for easier placement and installation. In addition, circuit engineers can design better circuits for power and sound quality as the tolerances of SMT components are superior to larger "through-hole" components. Because of their lower mass, SMT components withstand shock and vibration, making them perfect for audio designed for all vehicles. So use this amplifier in marine, powersports, vehicle, and RV applications.
