Description
Lots of power from a very small box
JL Audio’s JD500/1D mono amplifier will power your subwoofer with up to 500 watts RMS, so you can experience thunderous bass in your music. A variable low-pass filter and bass boost help you tune your sub to fit your system and sound its best. An optional remote level control lets you turn the sub up or down from the front seat.
Compact, but beefy
You know you’re holding a serious piece of sound equipment when you feel the heft of this tiny JD amp. JL Audio built it with sturdy, high-grade parts that ensure excellent heat management, provide high current flow, and deliver stable performance in almost any situation. You won’t find blinking lights or meters on the outside of these amps, but you will find oversized output transistors and rugged MOSFET power supplies inside. The high-mass aluminum heatsink keeps things cool enough to virtually eliminate thermal shut-downs.

Features
Monoblock Amplifier:ย The JL Audio JD500/1D monoblock subwoofer amplifier that has been optimized for low-frequency (10-150 Hz) amplification of connected subwoofers.
Note: The JD500/1D is not designed for driving full-range speakers, midrange drivers, or tweeters.
Class D Amplifier Circuit: The JD500/1D employs an advanced Class D switching design that allows it to produce 500 watts of clean subwoofer power while drawing significantly less current from your electrical system and generating less heat than a conventional Class A/B or Class B design.
MOSFET Switching Power Supply:ย The JL Audio JD series monoblock amplifier employs a rugged MOSFET power supply for outstanding reliability and operational stability.

High-Mass Heat Sink:ย A heavy extruded aluminum heat sink is designed to keep the JL Audio JD series amplifier in a comfortable thermal range during demanding operation. This high-mass, extruded heat sink removes heat from the amplifier circuitry, extending high-power operation. This improves reliability and reduces the frequency of a thermally related shut-down event.
Protection Circuitry:ย The JD500/1D’s protection circuitry automatically shuts the amplifier down if thermal limits are exceeded, a short-circuit is detected in the speaker wiring, or if low supply voltage limits are reached.
Status Indicator Lights:ย There are two status indicator lights on the right side of the amplifier.
- Power (Green):ย This LED lights green to indicate that the amplifier is turned on and operating normally.
- Protect (Red):ย The Protection LED lights red to indicate the amplifier’s protection circuitry has been activated to prevent product failure due to thermal overload, a short-circuit, or a dangerously low impedance connected to the amplifier’s outputs.
Controls
Input Sensitivity:ย The Input Sensitivity Control is used to match your source unit’s output voltage to the input stage of the amplifier for maximum clean output:
- Low-Level Input Range:ย 200mV-4V (RMS)
- High-Level Input Range:ย 2V-10V (RMS)
Low Pass Crossover: The JL Audio JD500/1D monoblock amplifier is equipped with a 12dB/octave Butterworth low-pass filter with variable frequency selection from 50 to 200Hz.
Bass Boost:ย The amplifier is equipped with a variable 0 to +12dB, 45Hz Bass Boost.
Remote Level Control:ย The JD500/1D is equipped with an RJ-25 connection for an optional wired RBC-1 Remote Level Control (sold separately) that allows volume level adjustment of the amplifier from the front of your vehicle.
Connections
Power/Ground/Turn-On Terminals:ย The monoblock amplifier features set-screw terminals for the power, ground, and remote turn-on connections. A 2.5mm hex-wrench is supplied for tightening/loosening the set-screws.
- Power and Ground:ย The JL Audio amplifier’s set-screw Power and Ground connections are designed to accept 8 to 4 AWG power wire.
- Remote Turn-On:ย The JL Audio JD series amplifier’s set-screw turn-on lead will accept 18 to 8 AWGย wire.
Note:ย The amplifier is not equipped with a fuse. An external 50-amp AFS, AGU, or MAXI fuse (not included) must be installed on the power wire. If a wiring kit is used which includes a fuse with a value other than 50-amps, the original should be replaced with a 50-amp fuse.
Speaker Output Terminals:ย The JL Audio JD500/1D features four set-screw speaker terminals for an easy parallel subwoofer connection. The monoblock amplifier’s four set-screw speaker terminals will accept 16 to 8 AWG speaker wire. A 2.5mm hex-wrench is supplied for tightening/loosening the set-screws.
Preamp Inputs:ย The monoblock amplifier features one set of stereo RCA input jacks. The amplifier features a dedicated Input Sensitivity gain control for these inputs. These controls are designed to match the input sensitivity of the JD500/1D to the specific signal source that is feeding it. The amplifier’s low-level input can be set between 200mV-4V RMS.
Speaker Level Inputs:ย The JL Audio JD500/1D also accepts speaker level signals, including those from factory systems (without the need for a line-output converter), via the supplied 10″ speaker-level harness. The amplifier’s high-level input can be set between 2V-10V RMS.
Preamp Outputs:ย The JD500/1D incorporates a pass-through preamp output sections so that additional amplifiers can easily be connected to the same signal feeding the monoblock amplifier. The preamp output signal is buffered to prevent noise.
