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

Worth the Upgrade
I had the original Fox box for about six years, going strong and happy with it, with no complaints. I had been eyeing this Ram Elite box for some time, going back and forth as I wanted the internal air volume to match the specs of my subwoofers, so I finally pulled the trigger. Let me tell you, it was a game changer. I have the new Elite box powered by a Sundown Audio SIA-3500-watt amp with two 12" Deaf Bonce SA-272s and a 370-amp Mechman alternator to back it up, and man, this box hits hard. Deeper bass, louder, and the lows it produces really woke up my system and shakes everything. If you are planning on or even thinking about getting this box, do it; you will be very happy and pleased.

Bass box! LoL
Love the fit and quality of this enclosure! I went with the Kicker CompQ subs and they dropped in perfectly! I definitely recommend Fox Acoustics

Fox Acoustics is a must for the gladiator!
Had the single 10" ported box and loved it! Of course bigger is better so upgraded to the dual 10 and it's great! Looks great and sounds great. Some tuning to do on my amp but it gets 5⭐️'s from me!
My box arrived 2 days ahead of schedule which was awesome. After opening it up you could tell this was professionally built. This is the 3 fix box I have owned and have zero doubt this thing will perform better than most things on the market today. I will update after install with pictures. Don’t hesitate buy one today you will get the best box that is built for your ride. They have exceptional customer service and have always answered any questions I have asked. Great company with beautiful built boxes.
In this truck, under the seat, nothing out there can beat it. Two Hertz MP300's in this box, off a Soundigital 3000.1 is Bass pleasure. As usual, great job Fox. GREAT JOB!!
