JL Audio XD300/1 Monoblock Class D Subwoofer Amplifier, 300 W V2

The amazing XDv2 amplifiers have become best-sellers because they are much more than just "small amplifiers". 

XDv2 amplifiers achieve efficiency exceeding 80%, meaning they produce far less heat and strain on your vehicle's electrical system than a conventional, large amplifier would generate. This efficiency advantage, combined with state-of-the-art microelectronic components, allows us to use very compact unitary cast alloy heat sinks. XDv2's also deploy our Advanced Thermal Rollback System to completely eliminate annoying thermal shut-down events. The end result is outstanding audio performance and reliability in a compact amplifier that is easy to install in the tightest spaces.

Beneath every XDv2's removable control cover, you will find studio-grade signal processing with fully variable crossover filters. Also included are our noise-killing, highly flexible differential-balanced inputs with remote level control capabilities via the HD-RLC remote level control (optional). Also included is automatic turn-on capability (via signal sensing or DC-offset sensing) and a dual-range differential-balanced input section able to handle a wide range of input voltage levels.

Some might just see a small amplifier, but for those who appreciate great audio, XDv2's reveal something huge.

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

This ultra-compact monoblock amplifier 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 the tightest space applications, including motorcycles and ATV’s (in a weather-tight compartment).

Targeted specifically for subwoofer applications, the XD300/1v2 includes a variable slope low-pass filter with continuously variable cutoff frequency selection from 50-500 Hz.

The XD300/1v2 also features the v2 Spec feature set, which consists of automatic turn-on capability (via signal sensing or DC-offset sensing), and a dual-range differential-balanced input section able to handle a wide range of input voltage levels. With the addition of an HD-RLC remote level control (sold separately), the amplifier's level can be directly controlled from the driver's seat.

This amplifier features a black powder-coat finish and a gasketed, brushed aluminum cover for the controls.
