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.

Fantastic sound quality.

Clint from Hudsonville, MI on 3/9/2017

Crutchfield Customer Review (What's this?)

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.

Pros: Great frequency response for a 12" subwoofer. Tight attack and release which sounds great with fast and heavy rock music. Natural clean sounding bass that makes acoustical bass sound like live instruments. Very good looking box that fit very nicely in my truck and still left a good amount of room left over

Cons: If this box somehow converted between a ported and a sealed box this product would probably be perfect. I thought it was slightly off that the first thing I notice when I looked in the box was a dead leaf and a small cap that looked like a toothpaste cap.This didn't adversely affect the product though it was just strange.

awesome subs

This thing is built so solid. It hits hard and deep. Love it

Pros: Loud. Can take a lot more power than I have. Nice looking box.

Cons: About the only complaint I have is its big but I knew that when I purchased it.

Clean, Tight Bass.

Crutchfield Customer Review (What's this?)

Just like the title says, clean tight bass. JL Audio makes a very good product. For the price, this box really impressed me. For a sealed box, I was surprised of how low this box hits, but still has the hard punch of a sealed box.

Pros: Great value for the price.

These sound great all around and hit hard when the bass hits!

Pros: look and sound awesome

Thump box!!!

Crutchfield Customer Review (What's this?)

This box delivers plenty of the low notes and tones you just don't hear normally.

High Definition Bass

BURG from Lumberton,NJ on 4/29/2014

Crutchfield Customer Review (What's this?)

This subwoofer is installed in a 2013 Honda Acoord EX-L V6 with NAVIGATION. It is powered by a 500 watt mono Soundstream REFERENCE 1.500 amp.The bass is clean and tight with excellent pitch definition. Synthesizer and pipe organ pressurize the air with Visceral impact! The CS212WXv2 is an outstanding value for the money. You would have to spend a substantial amount of money to get better performance!

Pros: Excellent fit and finish,looks great with the grill covers installed! After about 150 to 200 hours of break-in these woofers really open up! You get a wide deep soundstage that will put a big smile on your face!

Cons: NONE

Dope Subs

Wyatt R from Rochester, MN on 12/19/2013

Crutchfield Customer Review (What's this?)

I've had these subs for two months at this time. They sound great and they don't take up nearly as much space as my last sub did. They aren't the most powerful given that I don't have the best amp, but I plan on getting a better amp that will deliver more power to them and I will report back. So far I'm really liking them.

Pros: Don't Take Up Much Space, Great Look, Pretty Decent Sound

Cons: None So Far,

Great for the $

Angelos L from Hickory, NC on 10/23/2013

Crutchfield Customer Review (What's this?)

I bought these specifically to fit behind the third row seats of my 13 Pilot. I wasn't looking for earth shattering bass, but to add a little something extra when I don't have my kids in the car. It was perfect, and my third row seat can stay up!

Pros: Sounds good


Awesome Sound Awesome Price

Amazing BASS!!!!! Have it sounding like a concert in my ride!!!

Pros: It's all good


Powerful Sub

John T from Chicago, il. on 5/22/2013

Crutchfield Customer Review (What's this?)

Powerfull sub, sometimes overwelming. I had to set the sub volumne to -2 db!. Rather large, just bearly fits in my trunk.. Using with JL 369 watt amps in bridged mode. Clean bass.

Pros: Powerfull.

Cons: Just barely fits in my trunk

Just what i needed

AWal from Houston, TX on 5/15/2013

Crutchfield Customer Review (What's this?)

Got this box paired with a RF P300-1 amp pushing 412 watts RMS. The bass won't shake the Earth, but it sure does shake my little Civic like crazy. If you want the boom, then go with a ported or bandpass box. If you want clean bass, where you can hear the notes all nice and clean, then this is for you! I just hope my Civic doesn't fall apart on the road when it hits those lows! Have mercy...

Pros: Box has small footprint and is not too heavy. Cool JL logos on the box and woofers.

Cons: Mine was damaged slightly during shipping, but i know it's cause UPS throws stuff around like trash. Crutchfield hooked me up with a discount though, which is cool.


Clint from Chico, TX on 2/26/2013

Crutchfield Customer Review (What's this?)

This was an awesome sub, but i blew it but still its an amazing sound.

Pros: Great Back massage machine lol. Great Sound Quality

Cons: For me not enough power

JL quality @ not so much JL prices

poloboriqq from Austin, TX on 4/20/2012

Crutchfield Customer Review (What's this?)

I bought these subs not expecting much as they are JL Audio's least expensive subs and boy was I off. The subs hit hard and accurate bass notes and do not require much power. The box and subs look great and don't take up much space and they definitely look high end for not so much high end $$$$$$$$$$$.




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
