JL Audio PowerWedge MAX PWM112-WX

Overview: JL Audio PowerWedge Max subwoofer system combines JL Audio's rugged, great-sounding JL Audio WX subwoofer with a precisely engineered, USA-built enclosure/amp-rack, and a perfectly matched JL Audio J2 amplifier. Also included is a remote bass level knob that can be mounted in the front of your vehicle to give you full control over the subwoofer level.

Sealed Enclosure

Acoustic Suspension Enclosure: The JL Audio PowerWedge Max subwoofer system utilizes a sealed enclosure for tight, accurate, deep bass.

Quality Construction: The subwoofer enclosure features durable, American-made automotive-grade carpeting and premium JL Audio speaker wiring.

Amp Rack: The J2 amplifier is mounted to the PowerWedge Max enclosure behind a great-looking, CNC-machined amplifier shroud with a durable black textured finish.

Note: The amplifier shroud must be removed to access the amplifier's connections and controls.

Enclosure Application: This compact enclosure is ideal for a variety of vehicle sizes and feature an angled back panel to allow the subwoofer to fire toward the back of the vehicle with minimal loss of trunk or hatch space.

WX Series Woofer

WX Series: The JL Audio WX's are designed with a long excursion, DMA-optimized motor system, supported by JL Audio's patented Elevated Frame Cooling and a highly linear suspension. This means they deliver lots of low-distortion, high-quality bass with all types of music.

Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, the WX series woofer's motor remains linear in motor force over a very long range of excursion, and also maintains a highly stable fixed magnetic field in the gap over a wide power range. The result is vastly reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.

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

Rear Gasket: The woofer has an integrated foam rear gasket which provides an optimal seal when installing into the enclosure.

Long Excursion: The 12WX-4 subwoofer has 9.5mm of linear excursion, giving you louder bass with less distortion.

J2 Amplifier

Mono Subwoofer Amplifier: The JL Audio J2 250.1 is a class A/B monoblock subwoofer amplifier rated at 175 watts RMS x 1 into a 4Ω load.

Status Indicator Lights: There are two lights on the left side of the amplifier:

• Power: green LED indicates the amplifier is turned on and operating normally
• Protect: red LED indicates the amplifier has exceeded its safe operating temperature or detected a short in the speaker outputs

Controls: The JL Audio J2 250.1 amplifier provides the following audio controls.

• Gain: To accommodate the varying range of signal levels coming from today's factory and aftermarket radios, the JL Audio amplifier features an adjustable gain control (200mV-4V; Preamp input) or 630mV-20.5V; speaker-level input). This means that no matter what kind of radio is connected to this amplifier, the appropriate gain control adjustment can be made to ensure loud, clear, distortion-free music.
• Active Crossover: The low-pass crossover is continuously variable from 60 Hz to 240 Hz and cannot be bypassed. The crossover slope is 12 dB/octave.
• Bass Boost: The bass boost circuit is adjustable from 0 to +9 dB. The boost frequency is fixed at 45 Hz.
• Remote Level Control: The 14' cable attached to the included Remote Level Control plugs into the 3.5mm jack on the left side of the amp. When the module is connected, you can control the subwoofer volume from the driver's seat. The remote is designed to mount under the dash and measures:
  • Width: 2.513"
  • Height: 1.026"
  • Depth: 1.656" (2.325" including cable and knob)

Connections: The JL Audio J2 250.1 amplifier provides the following connections.

• Power and Ground: The Power and Ground connections accept 4 to 8 gauge wire; JL Audio recommends 8 gauge as the minimum size. The set-screw terminals are tightened/loosened using the included 3mm Allen wrench.
• Remote Turn-On: The remote terminal will accept 10 to 18 gauge wire. The set-screw terminal is tightened/loosened using the included 2mm Allen wrench.
• Speaker Outputs: The amplifier's speaker terminals are wired to the loaded woofer from the factory.
• Preamp Inputs: The amplifier features one set of RCA line level inputs. When using a single RCA input, JL Audio recommends using a Y adapter to feed a signal to both RCA jacks.
• Speaker Inputs: When connecting the amp to a head unit without line level outputs, use the included speaker level input harness.
• Preamp Outputs: There is a pair of preamp outputs so you can send audio to another amplifier in your system. The preamp output is not affected by the crossover or bass boost circuits.
