JL Audio M400/4 Marine 4 channel Amplifier

Small footprint, big kick

The M400/4 is small — less than 9" wide — but it delivers a massive amount of power from its compact chassis — up to 100 watts from each of its four channels. It owes these impressive specs to JL Audio's Class D NexD™ ultra-high-speed switching design, which eliminates the traditional drawbacks of a Class D amp design to deliver full-bandwidth performance, excellent efficiency, and very low distortion levels.

Great for a variety of applications

You can use this 4-channel amp for a variety of applications. Run two sets of high-performance coaxial or component speakers, or bridge the amp to 2-channel mode to get a couple of subs thumping. Or enjoy the best of both worlds by going 3-channel, and powering a sub plus your full-range speakers.

You can run the built-in variable frequency filters in high- or low-pass mode, depending on whether you're powering speakers or subs. JL Audio's optional wired remote lets you adjust the amp's level from the helm, while the preamp outputs make it easier to get signal to another amplifier in your system.
