DESIGNED FOR LIMITED SPACE APPLICATIONS

SHOCK-RESISTANT, WATER-RESISTANT AND BUILT TOUGH

EFFICIENT DESIGN FOR HIGH OUTPUT USES LESS ENERGY

COMPLETE SIGNAL PROCESSING SECTIONS ON BOARD

EXCEEDS INTERNATIONAL STANDARDS FOR SALT FOG AND UV EXPOSURE

2-YEAR WARRANTY

WHAT YOU'LL LOVE

POWER TO GO ANYWHERE

Housed in a tiny cast-aluminum chassis, MX amps are rugged, water-resistant (IPX7-rated) and ready to go where conventional amplifiers wouldn’t dare.

NexD ADVANTAGE

The highly efficient Class-D design reduces current draw and heat while generating loads of high-fidelity sound without straining small charging systems.

COMPLETE SIGNAL PROCESSING

For easy setup and system flexibility, a complete set of onboard filters and signal processing features is concealed behind every MX amplifier’s water-resistant control cover.

DIFFERENTIAL-BALANCED INPUTS

A versatile design accepts speaker level signals without a line-output converter — and delivers outstanding noise rejection while preventing alternator whine and other noises.

BUILT FOR THE ELEMENTS

The all-aluminum, powder-coated housing with marine-grade hardware inhibits corrosion, and a water-resistant security cover protects all controls from the harshest of seasons.
