The XDM1000/1 is a compact Class D monoblock subwoofer amplifier rated at 1000 W into 2 ohms at 14.4 V. It uses JL Audio's NexD switching design to fit that power into a chassis about 14.7 inches wide and just over 2 inches tall, which helps in tight car and boat installs. It is built with marine-grade materials, so it works in boats as well as cars. Against rival monoblocks it stands out for its small footprint, its 7 Hz to 500 Hz response and its protection circuitry rather than for built-in bass processing: there is no bass boost and no remote level control in the box.

Owners of JL Audio's XD and XDM amplifiers generally rate them highly for clean output, small size and cool running. The XDM1000/1 is bought mainly by people who want serious subwoofer power without a large amp board.
The JL Audio XDM1000/1 is a monoblock Class D amplifier built to power a subwoofer in a car or boat. It delivers 1000 W of continuous power into a 2 ohm load (14.4 V, 1% THD). Marine-grade materials make it suitable for either installation.
It uses NexD switching technology, which provides high efficiency and power from a compact chassis. Advanced Rollback Protection prevents thermal shutdown.
The low-pass filter has a variable slope and a continuously variable 50-500 Hz cutoff. A defeatable 30 Hz infrasonic filter (24 dB/oct.) is also included.
