JL Audio XDM300/1

Monoblock Class D car and marine subwoofer amplifier, 300 W x 1 @ 2 Ω / 200 W x 1 @ 4 Ω - 14.4V. This compact monoblock powerhouse employs high-speed NexD™ switching design to achieve unprecedented efficiency and impressive power output for its size. It is small enough to fit in most tight spaces, including small boats, pickups, motorbikes, and UTVs (in a weather-tight compartment).

Designed for car or boat installations, the XDM300/1 is built with marine-grade materials and features an exclusive dual-mode input filter for noise-free performance. Automatic turn-on capability (via signal sensing or DC-offset sensing) is also included for easy factory system upgrades.

Targeted specifically for subwoofer applications, the XDM300/1 includes a variable slope low-pass filter with continuously variable cutoff frequency selection from 50 to 500 Hz. With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (sold separately), the amplifier's level can be adjusted directly from the driver's seat or captain's chair.

Finished in a sleek black powder coat, all controls are protected beneath a gasketed, removable top cover for easy access.
