Crutchfield Customer Review (What's this?)

this is a wonderful item. You can have a speaker right underneath your seat without taking up any space and you still have room for the family!!!

Pros: save space, your speaker is hidden from view. People with ask you where is all of that bass coming from because there is no kicker box. lol

Cons: non, what more could you want. You have a hidden 10 sub that is right in the middle of your vehicle and out of sight.

Great box

Crutchfield Customer Review (What's this?)

I have a 2002 Chevy Abalanche and if you want a box that you can keep conceled you only have 3 options...a center console box which does remain hidden but you loose your center console storage, A midgate design wich i did not really care for the look or the cost of, and this box which is the least expensive of all three options. I went with this box because it does go under the back seat which is a big plus because I did not want to give up seating by having to put a box in the seat. I was a little worried that one 10" would be enough but I purchased a 10" Kicker Solo Baric Classic with a 500 Watt Sound Ordinance Amp and I am telling you it is plenty loud and hits plenty hard. i am not saying you are going to win any speaker comp with this little set up but I promise you will turn heads and be noticed. The box is well built and the perfect size for the speaker I purchased. The box fits great once I took out the plate from under the bottom of the seat. No big deal because the plate came out easy and did not support any weight. The only downside is you can only drop the midgate down maybe half way unless you take the box out, which is not hard to do and the box is light.

Pros: Perfect size and and great for staying conceled.

Cons: Cant lower midgate down all the way when installed in 2002 Chevy Avalanche

great bass!!

Installed this box with a 10" alpine and it sounds great. the box takes up no space at all and lots of bass for a single sub.

Crutchfield Customer Review (What's this?)

I've been wanting a small subwoofer in my truck ever since I got it, I've tried every "low profile" box on this site and all of them would end up requiring me to modify the backseat, which is something I am unwilling to do, not with this box!!. This box "drops" in under the back seat of the trucks or center seat if you have one of the suvs, rather than bolting down, the seat hardware keeps the box in place making it really easy to remove if you need the extra space for storage. My only complaint the seat cannot fold down while the sub is in place, but you can't have everything. You don't need a powerful Sub/Amp with this box (unless you want a lot of bass). In my box I have a Rockford Fosgate Punch S1 on a Sony 222 amp, Due to the box placement and design I get more satisfying bass than Ive gotten out of 12" Fosgate subs with factory matched amps.

Get everything you’ll need to enjoy your new Q-Customs Factory-fit Subwoofer Enclosures

You'll want a sub that is a match for this enclosure.
Don't skimp on the wire you will need to run from your new subwoofer enclosure to your amplifier.

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.
