JL Audio JD500/1 Subwoofer Amplifier

Powerful and Efficient Performance
Producing a remarkable 500 watts into 2 ohms (14.4V, 1% THD), the JD500/1 amplifier is a perfect choice for powering subwoofers in a budget-friendly audio system. Utilizing JL Audio’s proprietary NexD™ switching technology, this amplifier delivers significant real-world power with outstanding efficiency and ultra-low distortion, ensuring your system produces clean, powerful bass.

Intuitive Design and Versatile Features
The JD500/1 is thoughtfully designed for convenience and functionality. Its controls are housed on the input panel, while power and speaker connections are positioned on the opposite side of its robust extruded aluminum chassis. Key signal processing features include a 12 dB/octave low-pass filter with a fully adjustable frequency range from 50 to 500 Hz and a variable bass boost EQ for precise tuning.

Dual-range, differential-balanced inputs make the amplifier compatible with both line-level and speaker-level signals, offering versatility for various system setups. Automatic turn-on capability—via signal sensing or DC-offset sensing—simplifies installation, while preamp outputs make it easy to daisy-chain signals to additional amplifiers.

Precision Made Easy
The JD500/1 is equipped with an onboard LED-clipping indicator ring around the input sensitivity control, enabling quick and accurate input sensitivity adjustments without the need for specialized tools. For added convenience, the optional RBC-1 remote level control (sold separately) allows you to adjust the subwoofer level effortlessly from the driver’s seat.

Combining power, efficiency, and user-friendly features, the JD500/1 delivers outstanding performance and value for any audio enthusiast seeking high-quality bass on a budget.
