High-tech, high-power full-system 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 XDM500/3. 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 XDM500/3 three-channel amp can deliver 75 watts RMS to each of a pair of speakers while powering a sub with up to 300 watts. You can also switch to 2-channel mode and power a single high-performance speaker with 200 watts, while still driving a sub with 300 watts. 

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 just the bass channel.
