INSTALLATION TIP!
INSTALL THE SUB BOX IN THE TRUCK WITH THE SEATS OUT.
THIS ENCLOSURE IS HUGE AND IS DIFFICULT TO GET IN WITH THE SEATS IN THE TRUCK.
SEE PICTURES FOR SEAT LIFT KIT PART LOCATIONS.
DUE TO THE SEATS AND SIZE OF SUB BOX WE RECOMMEND HAVING 2 PEOPLE.
THIS ITEM IN NOT A 5 MINUTE DROP IN SUB BOX! IT REQUIRES INSTALLATION TOOLS AND THE ABILITY TO READ AND UNDERSTAND INSTRUCTION FOR BRACKET INSTALLATION. DIY IS NOT FOR EVERYONE, SO YOU MAY WANT TO SEEK PROFESIONAL INSTALLATION.
My customer was very happy with the way this box looked and how it didnt lose any space while providing excellent sound

This box hits hard!!
I bought this for my 02’ and installed the nvx vcw subs. Had to do a little trimming but was not hard. This box hits way better than i would of ever guessed. This box bangs .

great box
Great box sounded amazing with 3 kicker cvr 10s. The only issue we had was the metal logo on the front that says super duty made a lot of noise but one we put 3m foam tape on it noise went away. Will always keep fox acoustics in mind when looking for enclosure.

Fox Box 3 10 sub enclosure
The box is nice . It had to be modified to use the speakers that fox acoustic recommended for the box and instructions are very poor . Expected plug and play with video instructions for that amount of money. Also connection point for wires needs to be upgraded.
Sorry that you had a difficult time doing your install. DIY is not for everyone. The instructions are straight forward and they are on the listing along with other pictures. Trimming the hole for a sub with a cast frame is typical installation practice. There are 3 terminal cups that can handle 2000w each so they are more than adequate.

Was expecting better
The box fit great but its only 1/2" mdf and it does flex when turned up. Right now I have three sundown 10's on a jp23. When I upgrade the amp I will have to remove the box to add more bracing and change out the cheap terminals. On another note I was missing two bolts for the seat lift and it didn't come with any directions. For $700 i was expecting alot more
I know the description says it wouldn’t fit 2500/3500 but I tried it anyway. Fits great for me. 2020 3500 HD Denali dually crew cab. The rear seats are maybe 1/2-1 inch above their normal resting point so they are resting on the top of the box a bit but the sound this box produces is amazing. Running 2- 12” soundqubed HDS3.212 with temp 3000w amp will be switched to a sundown SFB 3000D soon. All mirrors and my heads up display shake like crazy. Will be recommending these boxes to everyone.
Installed dual 10 ported in my 21 DT 1500 quad cab. Fit perfect, no seat mods, finish looked great, just like the mil spec bedliner in my truck bed. I installed Audiocontrol spike 10s, sound quality is excellent and subs fit perfect.
Okay I have to say I've tried a few different boxes. You're cheap eBay ones and whatnot. This box surpassed all my expectations! I was so impressed with the build quality of it first off. Put this thing in got the seat raisers in and I'll tell you what. This thing blows me away how loud it is. I am a very happy customer. If you're thinking about it, just do it! You will not be disappointed

Great fit and good power
The amp fit easily behind the back seat of my 2023 1500 crew cab Hi Country. It has good power and doesn’t strain the electrical system too badly.
