JL AUDIO M700/5 5-Channel Class D Marine Amplifier

This little amplifier is excellent for a complete audiophile-grade, subwoofer-plus-four satellite system, and it fits comfortably in just about any boat’s weather-tight compartments.

NexD™ Technology: The breakthrough that makes this much power possible in such a small chassis is JL Audio’s NexD™ ultra-high-speed switching design, which allows for full bandwidth Class D operation with extremely low distortion and outstanding efficiency.

Combine with a subwoofer amp: With the M700/5, you can drive two pairs of quality component speaker systems with plenty of clean power (75W x 4 @ 4Ω), while also delivering a stout 300W of power to a subwoofer system.

Filters: The M700/5 includes a 12 dB / octave high-pass filter for one main channel pair, a 12 dB octave high-pass or bandpass filter for the other main channel pair, plus a variable slope low-pass filter for its subwoofer channel. All three filters offer continuously variable cutoff frequency selection from 50-500 Hz.

Remote control: With the addition of an HD-RLC remote level control (sold separately), you have the ability to control the level of two, four or all six of the amplifier’s channel levels from a remote location.

Built for the marine environment: This marine amplifier features white and gray powder-coat finishes, a gasketed cover for the controls and stainless steel hardware for durability in the marine environment.
