This PowerWedge handles up to 400 watts RMS, housing one 12" TW3 subwoofer that pounds out impressive low end.

JL AUDIO warrants the enclosure and the speaker to be free of defects in materials and workmanship for a period of two (2) years from the original date of purchase. For more detailed information you can check out the main product page and there is an owner's manual link there by the "What's in the box" section. This is for the full warranty information. Hope that helps.

Can this be wired to 4ohm?
[ Kevin  Sep 09, 2021 ]
1 answer
It is not possible to rewire this box to be a 4 ohm load
[ Paul  Sep 11, 2021 ]  Staff
what wire gauge should I use to connect it to the amp?
[ Alan  Aug 20, 2021 ]
1 answer
That will vary depending on the length needed to connect them. I recommend contacting an advisor by calling 1-800-324-9695 to get a personal recommendation
[ Paul  Aug 24, 2021 ]  Staff
Will it fit Behind back seat of a 2005 GMC crew cab truck?
[ Phil  May 04, 2021 ]
1 answer
Our research department didn't list the dimensions of the space behind the seat. I do not know if it will fit. I do know that it needs 21-1/4" width x 14-5/8" height x 4-1/2" deep at top x 7" deep at bottom of the box (without grille) and a depth of 7-3/4"
[ Paul  May 22, 2021 ]  Staff
Would this fit in a 1981 chevy c20 cab? Actually 2 of them since it doesn't look like you have a box for both? Also what would the actual power be if both were connected to your Kenwood kac 9106d?
[ ManyFacesTLS  Mar 04, 2021 ]

inused to drive an 84 c20 but never had that JBL in it- I have mine in a suburban. Based on what I remember about my c20 I do not think this would fit unless you're a shorter person and have the seat forward a bit. I'm 6'1" and there's no way it would have fit. The Grill does come off easy ( mine in fact came off in shipping) and that would give you a few more inches to play with- I'd worry about damage to the baffle. Just so your aware-these are awesome. I'm only running 1 and it smokes any other sub I've owned. 1 in a C20 will rattle your fillings loose.
[ Thomas  Mar 04, 2021 ]
Has anyone tried to fit this behind the back seat of a 2005-2020 Nissan Frontier Crew Cab?
[ Katsu  Jan 24, 2021 ]
1 answer
Our research department lists that there is little to no room behind the back seat in those Frontiers for a subwoofer. I doubt this or any subwoofer can fit behind that seat. However, we do have advisors that you can reach by calling 1-800-324-9695 who can check our current inventory if you have the measurements of the available space behind that seat
[ Paul  Feb 09, 2021 ]  Staff
Will this fit under the rear seats of a 2019 Ford F-150 Supercrew?
[ M  Dec 06, 2020 ]
1 answer
You can check to see if this will fit your vehicle by using our Outfit My Car tool: For additional 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.
[ Calvin  Dec 17, 2020 ]  Staff
Has anyone put this behind the seat of a 2017-2020 Tacoma?
[ Blake  Sep 15, 2020 ]
1 answer
Our research department concluded there wasn't enough room behind the seat to fit a subwoofer. While we don't keep records of where customers plan to install subwoofers, I do suspect that no one has put a subwoofer like this JL Audio behind the back seat
[ Paul  Sep 30, 2020 ]  Staff
Will this fit behind the back seat of a 2017 Tundra CrewMax?
[ Brooks  Sep 03, 2020 ]

It's fit perfectly behind the seat of my Toyota pick up 1994
[ JAMIL  Sep 04, 2020 ]
Howdy! Mine is in a Chevy Suburban- needless to say no issues, BUT a buddy was so impressed with the sound from this he got one for his 2016 Tundra crewmax. It fit, but was pushing pretty hard on the grill. It's pretty easy to take off. No issues after he took it off.
[ Thomas  Sep 04, 2020 ]
Will this fit 2012 Silverado 1500 crew cab under the back seat? Thanks
[ Otroman5  Jul 18, 2020 ]
1 answer
We do not have the measurements of the space under the seat to check if it can fit. I wish I had different news for you there. We do have the measurements of this box on its page should you get the measurements of the space under that back seat
[ Paul  Aug 04, 2020 ]  Staff
If I'm hooking this sub up to a JX 500/1D amp, what power wire gauge and speaker wire gauge should I be using?
[ Jon  Jan 22, 2020 ]
1 answer
4 gauge, as it's the largest that the amp's power and ground terminals will accept.
[ David  Feb 19, 2020 ]
Will this fit under a 2015 Silverado Crew Cab sear?
[ Lklynch  Nov 11, 2017 ]
3 answers
How much clearance do you have? It easily fits under my 2013 Nissan Titan Crew back seat. With a little room to spare as well. If it fits, it's a great sub.
[ Bret  Nov 12, 2017 ]
Very likely. I have mine under the rear seat of my 2012 silver 2500HD and it fits perfectly.
[ David  Nov 11, 2017 ]
It fits under my 2011 perfectly..I know a 15 and 11 are different body styles..I would check the measurements..thats what I did with mine before I bought it.
[ Phillip  Nov 11, 2017 ]
What is the best amp for this sub and what all do I need in order to hook it up in my truck?
[ Wade  Sep 24, 2014 ]
1 answer
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.
