JL Audio XDM300/1 (1) Channel Class D Monoblock Subwoofer Amplifier, 300W 98680

Monoblock Class D Car/Marine Subwoofer Amplifier, 300 W x 1 @ 2 Ω / 200 W x 1 @ 4 Ω - 14.4V

This little monoblock powerhouse employs our high-speed NexD™ switching design to achieve unprecedented efficiency and amazing power output for its size. It is small enough to fit in most tight space applications, including small boats, pickups, motorcycles and UTV’s (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 in boats or cars. Automatic turn-on capability (via signal sensing or DC-offset sensing) is also onboard 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 50-500 Hz. With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each 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.
