JL Audio XDM400/4 400 Watt RMS, 4-Channel Class D XMD Series Car/Marine Amplifier

High-tech, high-power amp for cars and boats

JL Audio combined the features of their best-selling M Series marine amplifiers and their high-tech XD Series car amplifiers to create the XDM400/4. The amp is built with marine-grade materials and features a selectable dual-mode power input filter for noise-free performance in either marine or automotive electrical environments. It plays your music with true fidelity and impressive impact without straining your vehicle's electrical system, thanks to JL Audio's proprietary NexD™ ultra-high-speed and efficient amplifier technology.

Versatile amp

The XDM400/4 four-channel amp can deliver 75 watts RMS each to four full-range speakers. Or you can bridge the amp to 2-channel mode and send 200 watts each to a pair of subs. You can also run two speakers with the front channels while driving a subwoofer with 200 watts RMS from the rear channels bridged together.

Works with almost any vehicle's system

"Differential-balanced" inputs help keep the signals clear of outside noise and allow you to connect this amp to just about any stereo, even some factory radios. The speaker-level inputs feature two auto turn-on modes to facilitate factory system integration. An optional wired remote lets you tweak the volume of the whole system from the driver's seat — or you can set it to control the rear channels only if you're using them to drive a sub, for example.
