JL Audio 2/3/4 Channel Marine Amplifier - M400/4

Product Details

JL Audio 2/3/4 Channel Marine Amplifier, Model M4004

Amazingly small in size, but huge in audio performance, the JL Audio M-Series amplifiers are the perfect solution for space-conscious installations or for anyone seeking affordable excellence in a mobile amplifier.

JL Audio's exclusive NexD™ switching technology achieves total amplifier efficiencies exceeding 80%, which means far less heat and less strain on your vehicle's electrical system than a conventional large amplifier. This efficiency advantage, combined with state-of-the-art microelectronic components allows us to use very compact unitary cast alloy heat sinks. As with their more expensive MHD siblings, the M-Series also deploy our Advanced Thermal Rollback System to completely eliminate annoying thermal shut-down events.

Beneath every M-Series amplifier's removable control cover, you will find studio-grade signal processing with fully variable crossover filters. Also included are our noise-killing, differential inputs with remote level control capabilities via the HD-RLC remote level control (optional).

Some might just see a small amplifier... But, for those who appreciate great audio, M-Series amplifiers reveal something huge.
