Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
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
WX Series Woofer
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
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.
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
- 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
- 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
- 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.
