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
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.
Very happy with this sub box. You won’t find a better sounding box for the Tundra. It fits great and has more mounting depth than any other box on the market. I went with two 10” JL W1 v3 with an Alpine S2-60M pushing it and it’s perfect. They really sound good and hit harder than I was expecting.
I started with a TT single 10 box, the sound was horrible and it rattled being plastic, tried building my own and that was a fail. Took a chance and Ordered the Fox box along with two Sundown 10's and the Sundown 1250 amp. the sound is incredible and so freaking loud. I had to turn it way down for daily driving. I am finally happy with my system after having the truck for a year and a half.
I have nothing but love and respect for the people at Fox Acoustics I've gotten two of their Sp-12 unspecified boxes and I am simply blown away by the lows and amount of air these babies move, and they sound GREAT, I can park 2 blocks away and my friends still say everything in their house is rattling 🤣🤣 it's so obnoxious I love it, and the 1.25 inch double baffle on the front is 👌 mint, I'd recommend these kind fellas at fox acoustics to anyone interested in being Loud for a good price and receiving great service. Thank you guys so much again - Nick

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