Amplifier

Monoblock Amplifier: The JL Audio JX500/1D monoblock subwoofer amplifier that has been optimized for low-frequency (10-150 Hz) amplification of connected subwoofers.

Class D Amplifier Circuit: The JX500/1D 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: The JL Audio JX series monoblock amplifier employs a rugged MOSFET power supply for outstanding reliability and operational stability.

Amplifier Ratings:

High-Mass Heat Sink: A heavy extruded aluminum heat sink is designed to keep the JL Audio JX 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 thermally related shut-down event.

Protection Circuitry: The JX500/1D'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: There are two status indicator lights on the right side of the amplifier.

• Power (Green): This LED lights green to indicate that the amplifier is turned on and operating normally.
• Protect (Red): 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: 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: 200mV-4V (RMS)
  • High-Level Input Range: 2V-10V (RMS)
• Low Pass Crossover: The JL Audio JX500/1D monoblock amplifier is equipped with a 12dB/octave Butterworth low-pass filter with variable frequency selection from 50 to 200Hz.
• Bass Boost: The amplifier is equipped with a variable 0 to +12dB, 45Hz Bass Boost.
• Remote Level Control: The JX500/1D 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: 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: The JL Audio amplifier's set-screw Power and Ground connections are designed to accept 8 to 4 AWG power wire.
  • Remote Turn-On: The JL Audio JX series amplifier's set-screw turn-on lead will accept 18 to 8 AWG wire.

• Speaker Output Terminals: The JL Audio JX500/1D 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: 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 JX500/1D 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: The JL Audio JX500/1D 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: The JX500/1D 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.

Amplifier Dimensions:

• Width: 7.829"
• Height: 2.117"
• Depth: 7.67"

Subwoofer

Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, 10W0v3-4 motors display linear force over a long excursion range, and also maintain a stable fixed magnetic field in the gap over a wide power range. The result is reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.

Elevated Frame Cooling: The elevated frame design of the 10W0v3-4 delivers cool air through slots directly above the top plate to the voice coil. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.

Rear Gasket: The woofer has a rear gasket to provide an optimal seal when installing into the enclosure.

Long Excursion: The 10W0v3-4 subwoofer has 11.4mm of linear excursion, giving you louder bass with less distortion.

Enclosure

Materials: The Sound Ordnance BB10-64S Bass Bunker is an unloaded, hatchback-style sealed enclosure for one 10" subwoofer. It is constructed of 5/8" MDF (medium-density fiberboard), covered in black carpet.

Internal Box Volume: The enclosure has 0.69 cubic feet of airspace.

Terminals: The BB10-64S is equipped with two pair of spring-post speaker terminals mounted in the rear panel, offering wiring flexibility when used with a dual voice coil woofer. The spring terminals will accept bare wire up to 10 gauge, pin connectors, and single banana plugs, but are spaced too far apart for dual banana plugs. Inside the enclosure the terminals have two attached 15" lengths of speaker wire for connecting the subwoofer.

Brackets: Brackets for securing the enclosure to your vehicle are recommended.

Enclosure Dimensions:

• Width: 13.125"
• Height: 12.25"
• Depth (bottom): 12.625"
• Depth (top): 9.5"
