Compact Footprint

Benefits:

  • They fit nearly anywhere!
    • JD250/1 & JD500/1: 9.50 x 7.50 x 2.10 in. (242 x 190 x 53 mm) JD1000/1: 11.40 x 7.50 x 2.10 in. (290 x 190 x 53 mm)
  • High-mass heat sink improves thermal capacity leading to reduced incidence of shut-down events.

NexDTM Switching Amplifier Technology

Benefits:

  • JL Audio's high-speed switching technology delivers outstanding fidelity with very low noise and distortion.
  • Exceptional efficiency results in reduced current draw and heat, permitting reliable high power output within a very small chassis.
  • Specifically optimized for subwoofer applications (7 Hz - 500 Hz bandwidth)

Complete Signal Processing Package

Benefits:

  • 12dB/octave low-pass filter, non-defeatable, with fully variable filter frequency selection from 50-500 Hz
  • Adjustable 0 to +12 dB Bass Boost EQ @ 45 Hz
  • Remote level control with optional controller (RBC-1)
  • Preamp outputs (buffered, pass-through type)

Dual-Range, Differential-Balanced Inputs and Automatic Turn-On Capabilities

Benefits:

  • NO NOISE! Outstanding noise rejection prevents alternator whine and other noises.
  • Accepts line-level or speaker level signals (up to 8V RMS), including those from factory systems, without a line-output converter
    • (LOC): just splice wires to a pair of RCA ends or RCA cables.
  • Automatic turn-on option via Signal-Sensing or DC-Offset sensing

Integrated LED Clipping Indicator for Easy Setup

Benefits:

  • Simplifies input-sensitivity setting by providing accurate visual feedback of output clipping level.
    • Disconnect one speaker output wire
    • Play full-scale (0 dBfs) sine-wave through audio system, with head unit at 3/4 volume and tone controls set flat.
    • Adjust input sensitivity until light turns on, then back off slightly.
  • Separate, top-mounted LEDs report overall status and condition

Monoblock Class D Subwoofer Amplifier, 500 W x 1 @ 2 Ω / 250 W x 1 @ 4 Ω - 14.4V

Designed to produce a whopping 500 watts into 2 ohms (14.4V, 1% THD), the JD500/1 amplifier is a great solution for powering subwoofers in a cost-conscious system. JL Audio's proprietary NexD™ switching technology delivers large amounts of real-world power output with excellent efficiency and ultra-low distortion.

The JD500/1’s controls are located on the input panel. while the power and speaker connections can be found along the opposite end of its extruded aluminum chassis. Signal processing features include a 12 dB / octave low-pass filter, with continuously variable frequency selection from 50-500 Hz, and a variable bass boost EQ. Dual-range, differential-balanced inputs are also on-hand, capable of accepting line-level and speaker-level signals. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard, along with a set of preamp outputs so you can easily pass signals to another amplifier. 

The JD500/1 is also equipped with an onboard LED-clipping indicator ring, surrounding the input sensitivity control. This useful feature lets you set your amplifier’s input sensitivity, quickly and accurately, without special equipment. With the addition of an RBC-1 remote level control (sold separately), you can control the subwoofer level from the driver’s seat.
