JL Audio XD300/1V2

Description

The XD300/1V2 is a 1-channel amplifier from JL Audio. Comprehensive with features such as a variable low-pass filter and exemplary output power through JL's high-speed NexD™ switching design, this monoblock unit combines unrivaled engineering with a solid structure. With optional add-on features like the HD-RLC remote control for convenient control right from the driver's seat and a strong black powder coat finish with a sealed, brushed aluminum cover, this model sets a new standard in amplifier technology.

Features

• Monoblock subwoofer amplifier in Class D, 300 W x 1 @ 2 Ω / 200 W x 1 @ 4 Ω - 14.4V
  
• This ultra-compact monoblock amplifier utilizes JL's high-speed NexD™ switching design to deliver unprecedented efficiency and astonishing output power for its size. 
• The XD300/1v2 was specially developed for subwoofer applications and contains a low-pass filter with variable slope and continuously adjustable cut-off frequency from 50 to 500 Hz.
  
• The XD300/1v2 also features the v2 Spec feature set, which consists of an auto power-on function (via signal sampling or DC offset sampling) and a dual-range differential balanced input section that can handle a wide range of input voltage levels.
• With an additional HD-RLC remote control (sold separately), the level of the amplifier can be controlled directly from the driver's seat.
  
• This amplifier has a black powder coating and a sealed, brushed aluminum cover for the controls.
