JL Audio Jd500/1 Monoblock Class D Subwoofer Amplifier, 500 W
Product Overview
Extended 1+1 Year Brand Warranty
Monoblock Class D Subwoofer Amplifier, 500 W x 1 @ 2 Ω / 250 W x 1 @ 4 Ω - 14.4VDesigned 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. Our 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.

Frequently Asked Questions (FAQ)
Q: Can I connect the JL Audio JD500/1 directly to a factory stock car radio?
A: Yes! The JD500/1 features differential-balanced high-level inputs along with built-in DC Offset and Signal-Sensing auto turn-on modes. This allows it to tap directly into factory speaker wires without requiring a separate line output converter (LOC).
Q: How does the built-in LED clipping ring help during installation?
A: The LED ring surrounding the input sensitivity control glows red when the amplifier senses output clipping (distortion). This lets you visually set your gain to the highest possible level without sending distorted, potentially damaging signals to your subwoofer.
Q: Can I adjust the bass level from the front seat?
A: Yes. The JD500/1 features a dedicated port for the optional JL Audio RBC-1 wired remote bass control (sold separately), allowing you to adjust subwoofer volume on the fly from your dashboard.
