Monoblock Class-D Subwoofer Amplifier, 300-Watt Mono @ 2-Ohm or 200-Watt Mono @ 4-Ohm
This ultra-compact monoblock amplifier employs JL's 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.
