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 PROFESSIONAL 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
This is by far the best box I’ve ever used. I’m currently running 10” P3D4’s on a R21200x1 @ 1 ohm and I’m very impressed. The 12” subs that will eventually go in are being debated but I know this box will handle them.
8" Fox Box is unbelievable! Extreme Quality! Cut out hole is perfect for my standard 8" Kenwood MRN 2053 coaxial speakers (7 1/16)!!!! Diameter of speaker grill is exactly the same as box width. The box's finish seems perfect and to be very waterproof. I couldn't be happier with my purchase!!!!!

Ram 3500 Mega Cab Box
Just recently bought this box for my 06 mega cab, box is very well built and the finish on it looks amazing. Upon sliding it into place it fits very snug. The craftsmanship into these boxes is top notch.
Only downfall was I had to travel to the states to pick this up due to them not shipping outside of the USA, but the road trip was worth it

Awesome box!
Very happy with 2 JL Audio 10w0’s powered with an RD500/1. Well made box that gets super loud. If you’re thinking about it, pull the trigger! Thanks Fox

Sounds great in my 2021 F150
Previous setup was a pre loaded Skar audio box with dual shallow 12's. On a 1000.1 amp. I think that box is tuned to around 38 or 40hz.
And that setup just wasnt capable of hitting lows at all, super punch, not what i wanted.
After some research i stumbled upon this box, seemed to be the lowest tuned pre built box on the market for the F150.
Really wated to get the Sundowns for the best sub they recommend but couldnt get a sundown anywhere. So the research continued.
I ended up purchasing dual CT Sounds Strato 10" D4 subs. 1,250w RMS each. And got a Taramps 3000.1 on some 0 gauge audio CCA power wires.
The box needed a little bit of widening for the 2 holes the sub go into, the cage of the sub hit, but after making some slots the sub slides right in and just barely has clearance around the magnet.
Compared to the old setup, this one is deep and powerful, but not in a violent punchy way, its more refined, controlled and you feel it. I was kinda expecting it to be more violent with the increase in wattage, but i think that wattage is what im feeling, instead of it being violently punchy.
I have a 2021 F150, didn't do the big 3, stock alternator, i got a nice volt meter and while blasting it as much as i can without clipping the voltage stays at 14v+ at all times, I do have a H8 AMG battery.
Overall, great box, like the rhino coating because it stays cleaner than carpet, but it does move around a bit on my rubber mats, need to figure out a way to get it to stay in place. Would recommend if you lookin for deeper sound!
Never going back to shallow subs.
