F250 Platinum

Box fits really nice for as big as it is. Would prefer it to be all one piece like the the 4-10 box. This one is modular and the rear section bolts together. It sounds phenomenal with the woofers and amp that I choose. Most cost effective under-seat big woofer option.

Cant get dimension so cant even decide .

Guess I'm used to Amazon and other sites where you can review dimensions of all products. Simply asked for dimensions and person in chat was quite rude.
While the year of the truck is older, it looks close enough that I could have modified the seat and still used the box.
Fox refused to provide any info for me to even consider options.

First off Patrick has a 2013 truck and the listing clearly states 2015+.
The 2009-14 body trucks do not have a space on the driver side to accommodate the rear module of the sub box. No amount of seat modifications can change that. Patrick is clearly a 'special' person who thinks that doesn't apply to him. We even replied back that he would have to take a sawsall to the floor of his truck but he still insisted that he wanted the measurement to check anyway.
So, no. I'm not going waste half an hour unboxing a product, taking a bunch of measurements then repacking it, for something that I know will not fit his truck. But like a little Karen he wants to leave this review because he couldn't get what he wanted.

F150 3-12s box

This box looks and sound amazing, running 2 sundown classic 12s with a block off plate and sundown sia 2500 amp, the seat lift that comes with it is perfect, still have leg and headroom and functions just like stock, might add the 3rd sub later but the 2 is plenty for now, this is my 3rd Fox box, it's hard to beat their quality!!!

BADASS UNDERSEAT BOX FOR FULL SIZE 12’s

This box was exactly what I was looking for when I bought my 17 crew cab duramax. I was thinking I was either going to have to have a box specialty built or be stuck running shallow 12’s until while searching one night I stumbled onto this wonderful creation. I’ve had SA V2 12”s in it (3 sets blown) and SKAR EVL 12’s in my box (have only blown 1 set) I travel a lot for work so they are usually rocking the whole way anywhere from 9hr trips to 27hr trips and the Skar have smoked at least 10 times and keep on going. I have only the driver side in my truck right now and have bought a CT SOUNDS STRATOS 12 for the passenger side to try the brand out but haven’t installed it yet only jamming with the one right now and it sounds amazing. I pulled into a local store that sells car audio and when I pulled into the install area I turned it up (SA V2 12’s installed at the time) and everyone that worked there came running out to see who was rattling the building and asked “that’s a down fire box? I can’t believe it, let me see” now, I am running a Rockford Fosgate constant power 1500 watt amp on each 12 with a big 400amp alternator and big 3 installed but they were amazed that a down fire box was hitting like that and full-size 12’s were able to fit under the seat of a crew cab truck. The only thing that I thought should’ve came with the package when I purchased both boxes (driver and passenger side) that I see comes with the 4-8” under seat box is the connector plates. How can I get my hands on a set of those plates? So the box will quit sliding apart. Pic below

Box slams! Was a little longer to get my order due to the hurricane moving through the area but was well worth the wait. Wouldn’t hesitate to buy another from them again in the future.

Great Box

The box is great. It fits well and sounds good. I dinged them a star for it taking a month to receive. I feel if I hadn't sent an email inquiry I'd still be waiting.
Also, they never responded to my email. Two days after I got a tracking number though.
If you are impatient or in a hurry, be leary. I wasn't since the woofers were on backorder too.

Please read the top of our website where it states that we are running 2-3 weeks on lead time. 3 week lead time plus shipping time is going to put you right at a month. Quality takes time and we delivered as advertised.

Sounds great

Makes the cab rumble! Love the sound. Thanks for the custom fit.

Another win

This is my third foxbox for a 5th gen ram. Had a quad cab up fire, then the down fire box for 10's in a crew now the up fire 12's. All solid units but the 12's are the ticket with some sundown classics. Unbelievable for a prefab at this price.
