The MB Quart NA4-400.2 Nautic is a compact 2-channel amplifier engineered for reliable, high-output performance in marine and powersports environments. Built around a highly efficient Class D topology, it delivers up to 400 watts of total power while maintaining a small footprint that fits easily into tight installation spaces. Designed for harsh conditions, the amplifier features IP67-rated protection along with fully potted internals. This sealing process protects critical components from water, dust, vibration, and corrosion, making it ideal for boats, UTVs, and other outdoor applications where durability is critical. An aluminum heatsink further improves thermal management, allowing the amplifier to perform consistently under load. On the audio side, MB Quart’s Q-Stasis low-noise preamp circuit helps reduce incoming signal noise, improving clarity across the entire frequency range. With a response of 6Hz to 29kHz and a signal-to-noise ratio greater than 105 dB, the NA4-400.2 is capable of clean, full-range sound reproduction. Variable high-pass and low-pass crossovers (12 dB/octave) provide flexible tuning, making it easy to dial in performance for a wide range of speaker setups. Installation is streamlined with quick-connect power, speaker, and RCA terminals, along with corrosion-resistant nickel-plated connections. Integrated protection circuitry monitors thermal, overload, DC, and speaker faults, with LED indicators for system diagnostics.

Clarion amplifiers feature uncompromising resistance to magnetic noise, thereby minimizing distortion, as well as high quality terminals to offer low electrical and contact resistance. Easy subwoofer system configuration is possible with the embedded high pass filters. The result is high quality sound you can enjoy in a variety of systems. By utilizing corrosion resistant RCA and Connectors, XC series amplifiers offer improved durability and reliability in harsh environments. The XC series amplifiers are true marine amplifiers with efficient aluminum heatsinks and locking power terminals for the harsh marine conditions. There’ s only one way for Clarion’ s main units to deliver unyielding power output and linearity: MOS-FET amplification, or Metal Oxide Semiconductor Field Effect Transistor amplification. Smaller and more efficient than conventional power supplies, a MOS-FET amplification circuit delivers power with less distortion and zero On/Off switching noise. This means you can crank up the volume or set it to easy listening. Either way, your sound will be crystal clear.
