1400-Watt All-In-One Marine Audio Engine

The MTX MA1400.5 is a high-performance, 5-channel marine amplifier designed to be the single-chassis solution for an entire boat's audio system. Engineered to provide a complete "Sound Experience," this Class-D powerhouse features four dedicated full-range channels for speakers and a high-output mono channel specifically for a subwoofer. Built to thrive in the unforgiving marine environment, the MA1400.5 utilizes a conformal-coated circuit board and stainless steel hardware to shield internal components from moisture, salt, and corrosion, ensuring your music stays loud and clear whether you're at full throttle or anchored at the dock.

It is equipped with professional-grade tuning tools, including Tiffany-style RCA inputs, independent crossovers for all channels, and a built-in clip detection light to assist in perfect gain optimization. With its compact 14.5" chassis and integrated thermal, short, and voltage protection, the MA1400.5 offers a "rock-solid" foundation for any premium marine audio build.
