JL Audio XDM500/3 3-channel marine amplifier

Description

The XDM500/3 uses JL Audio NexD™ Ultra High Speed Class D amplification technology, which delivers high efficiency and clean sound reproduction with lower heat output. The main channels provide enough power to drive component or coaxial speakers, while the separate subwoofer channel allows a subwoofer to be connected as part of one compact system.

The amplifier offers two full-range channels with 75 W RMS per channel at 4 ohms, plus a separate subwoofer channel with up to 300 W RMS at 2 ohms. This makes the XDM500/3 well suited to setups that use front or satellite speakers together with a single subwoofer.

The JL Audio XDM500/3 includes adjustable filters that allow precise tuning of the system. The main channels have a high-pass filter and the subwoofer channel has a variable low-pass filter. The amplifier also supports remote level control with an HD-RLC or MHD-RLC controller.

JL Audio® XDM500/3 is an ideal choice for anyone who wants to build a high-quality, compact 2.1 system for car, marine or powersport use, driving both speakers and a subwoofer from a single amplifier.
