An excellent combination

The CS212-WXv2 BassWedge contains two 12" WXv2 subwoofers that together handle up to 400 watts RMS, loaded into a specially built sealed enclosure. You'll enjoy punchy, detailed bass without taking up too much room in your vehicle's trunk or cargo area.

BassWedge CS212-WXv2 enclosure

Solid MDF enclosure

JL Audio uses state-of-the-art automated woodworking equipment to fabricate the high-quality MDF enclosure with rugged automotive carpeting, nickel-plated push terminals, and solid internal wiring.

Sounds very nice paired with the JX250/1d. Very clean, deep, and great quality. They can keep up with a lot of bass guitar and kick drum and they have a great attack and defeat response.

Hands-on research

Product Research


Overview: The JL Audio BassWedge sealed subwoofer enclosure is designed around two of JL Audio's 12" WXv2 (4Ω) subwoofers, delivering tight, powerful bass. The MDF enclosure is covered with gray carpet and has a JL AUDIO logo embroidered across the top.

Speaker Terminal: The enclosure uses one pair of high current spring posts; the subwoofers are internally wired in parallel to a single terminal, presenting a 2Ω load to the amplifier. The posts are located on the left side of the box and will accept pin connectors, single or dual banana plugs, or bare wire up to 10 gauge.

WXv2 Woofer Features:

  • Dynamic Motor Analysis (DMA): DMA is a JL Audio proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the woofer's motor remains linear in motor force over a long excursion range, and maintains 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 12WXv2 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 an integrated foam rear gasket which provides an optimal seal when installing into the enclosure.

Optional Grille: The optional SGRU-12 grilles (item number 136SGR1231, sold separately) can be added to protect the woofer cones.

6 questions already asked

Yes this box can do the job bless?? [ Burchelle  Feb 23, 2017 ]
I'm not sure, if your just replacing the 12 with 12 they should fit, but a far as specs I couldn't tell you off hand. The site should have them. [ Kevin  Feb 23, 2017 ]
Yes they should fit in the box. [ Latasha  Feb 23, 2017 ]
Depends on if you are running at 2 ohm or 4 ohms. I have a Rockford Fosgate mono amp running 500 watts at 2 ohms (subs are wired in2ohm configuration from factory I think) ..if my subs were wired in 4 ohm configuration, the amp would only put out 250 watts. Look up the spec on the woofer and it should site max watts... max wattage only will be present when your volume knows are fully turned up on the radio.. so you could oversize the amp but run the risk of Blowing subs when you turn it up toon much. Cheers, Sean [ SEAN  Dec 01, 2016 ]
Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy  Jan 10, 2016 ]  Staff
I'm not to sure because I placed mine in a 2006 Mazda 6. [ Jason  Jul 29, 2015 ]
Yes it would be fine, but I look for something that wouldn't take up a seat, maybe something that would fit under. [ Kevin  Jul 28, 2015 ]
Any 500w mono amp will/should work fine [ Jeffery  Jul 13, 2015 ]
I have a kenwood 500w mono amp, has given me no problems over the past year. Just don't turn the gain all the way up. [ Jeffery  Jul 13, 2015 ]
I use a Boss Amp I got off here super cheap. Has works good for 2 years and still going. The bass is great too. [ Christian  Jul 13, 2015 ]
Alpine and jl audio make amps that are a good match for this subwoofer. Crutchfield has several in stock. [ FREDDIE  Jul 13, 2015 ]
I paired mine with a JL Audio JX500/1D. Just make sure to tune your amp with a 1kHz test tone so you don't overpower your drivers. [ C.U.N.L  Jul 13, 2015 ]
If you only need the amp for the subwoofer then a JL 500/1 would be perfect! [ Olinda  Jul 13, 2015 ]
For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle. [ Krissy  Jun 07, 2014 ]  Staff
