Overview: Marine Amplifiers

JL Audio MHD Marine Amplifiers MHD
"Small" is not the real story here.

Engineered to deliver real world-class sound quality with astonishing power and efficiency, MHD amplifiers perform like no other marine amplifiers, period. Encased in a compact, stackable chassis design, MHD amplifiers employ JL Audio's proprietary Single Cycle Control™ switching design with our exclusive R.I.P.S. (Regulated, Intelligent Power Supply) technology to generate outstanding power output, with remarkable fidelity, over a wide range of speaker impedances. Our signature Advanced Thermal Rollback protection system eliminates annoying thermal shutdown events to keep the music playing, even under the most demanding conditions. Protected beneath a gasketed cover are noise-rejecting, differential-balanced inputs and a full complement of studio-grade processing features to make system setup a breeze. A port for the HD-RLC remote level control (optional) allows amplifier level adjustments from the helm. Learn more about MHD amplifiers.

JL Audio MX AmplifiersMX Amplfiers

Compact, powerful and versatile, MX amplifiers are built to deliver amazing sound from the smallest of spaces, plus they're water-resistant.

Employing JL Audio's highly-efficient NexD™ Class D technology, MX amplifiers generate lots of high-fidelity sound, while being kind to small charging systems. Housed in a cast aluminum chassis, MX amps are ultra-compact and water-resistant, making them perfect for installations in boats and small watercraft. Onboard filters and signal processing allow easy set-up and system flexibility. The optional M-RBC-1 (sold separately) allows subwoofer level control (MX300/1 or MX500/1) remotely from the captain's chair. Learn more about MX amplifiers.
