Our take on the Q-Customs Factory-fit Subwoofer Enclosures by Crutchfield's Dominic DeVito
Q-Logic designed this black Q-Customs enclosure to hold one 10" Type 1 subwoofer, giving you factory fit and finish plus great sound and durability. It fits under the driver's side rear seat of your 2000-up Chevrolet or GMC pickup, or under the middle seat of your General Motors SUV, without sacrificing any space.
Note: This enclosure will only work in vehicles with second row 60/40 split bench seats. It will not work in vehicles with second row captain's chairs (bucket seats with fold-down armrests). Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this model is compatible with your vehicle.

6 questions already asked
1 answer What is the depth where the sub goes? I want to make sure the sub-woofer I purchase for it fits. I did buy a dual 12 inch enclosure, but was informed that because of the limited space in the box the bass would be very limited. I was told that I could still use the box, but I would have to buy 2 shallow mount 12's, but if this box is as good as the reviews say, I'd rather go this route. Thank you for your info. [ Clitn Feb 23, 2017 ]
Thanks for your question. The maximum mounting depth for the sub would be 5 15/16". Your sub must not exceed this dimension in order to properly mount in this enclosure. Hope this helps. [ Kenny Feb 24, 2017 ] Staff
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 help determine fit and what you will need for an installation in your vehicle. [ Kenny Jan 28, 2017 ] Staff
The length is 26 1/2 by 6-1/2 height and 16 inches wide. Buy far the best sub box I have ever had, top quality good sound, love it [ LAYNE Apr 04, 2016 ]
It's listed right on the page, under details. [ Brad Apr 01, 2016 ]
The box prevents the seat from laying completely flat. The nice thing is that you can just disconnect the speaker wires to the box and move it within seconds. [ WES Jan 18, 2015 ]
Hi John, after you install the enclosure, you can't lay the back seat flat completely, you have to remove the enclosure, but is not to hard to do it , my enclosure is installed in a Avalanche 2007 , so the back panel to make the cargo space bigger doesn't lay completely flat. But again is not hard remove it, because doesn't need be attached with screws to avoid moves when you are driving . [ JESUS Jan 18, 2015 ]
The seat bottom will hinge forward but the seat back will not lay all the way down flat. It goes 1/2-3/4 of the way down. It is my only complaint. [ STEVEN Jan 18, 2015 ]
It prevents it from laying flat [ Brian Jan 18, 2015 ]
To clarify the above answer, it is in regards to a 4 door chevy pickup. [ BROCK Jan 18, 2015 ]
The enclosure prevents the back seat from laying completly flat. [ BROCK Jan 18, 2015 ]
Yes it does put it in a 02 tahoe w a kicker 10 hits hard sounds like 2 12s. [ chance Jan 18, 2015 ]
I used the space behind the rear seats for the amps. Its the only place you have left if you don't want to mount an amp under the passenger side rear seat. If you chose to go under the seat you will have to pull the jack and other tools then grind off the mounting bolts which secured them. [ RAFAEL E Aug 11, 2014 ]
This box takes up the middle and drivers side of the rear seat. I have my amp under the passenger side of the seat. As long as your amp can fit under that area it can go under the seat. [ JASON A Aug 08, 2014 ]
I mounted the amp on the passenger side rear seat. It is under the seat and I was able to run all of the cables under the carpet including the giant power wire and all of the RCA cables. The box only goes under the 60% side. [ Heart of Texas Aug 08, 2014 ]
Sorry but I can't help my truck got stolen the day before I recived the box [ oscar Apr 01, 2014 ]
It does not need a "special" sub, but it does need one that has a mounting dimension that doesn't exceed the box depth. [ BROCK Mar 20, 2014 ]
Make sure the sub you chose has the mounting clearance for this enclosure and will work within a small sealed enclosure. This will limit the choices you have. I went with a type R sub from Alpine knowing the top mount depth was going to be more than the enclosure could handle. After building a spacer to lift the sub out of the box everything worked out excellent. Just a little more work. [ RAFAEL E Mar 20, 2014 ]
The q logic box will hold any ten inch sub so long as the mounting depth is not exceeded. The box gives max depth on its specification and dimension info and subs will list this dimension also. It also sounds pretty good. Just don't expect any competition winning bass. [ STEVEN Mar 19, 2014 ]
I installed a 10" Polk sub and this fit into the enclosure perfectly. I the mounting diameter of the sub you are installing is 9.125" or less no modifications are needed. I it is greater you will nee to cut the rubber QX ring. This is no big deal and takes about 5 seconds. The only thing I did differently than the instructions stated was drilling the sub mounting holes. This made installing the mounting screws much easier. I had the sub in the enclosure in less than 15 minutes. All I needed to install it into my truck was to raise my rear seat and lay it in. The unit sounds great. Hope this helped. Bob.
