OMG Great box and sound
This box is Bada** !
The fit was perfect and it came with very nice powder coated mounts that allow the box to be mounted nice and high. The tops still fit back there with ease.
This box catches a wide band of notes and shakes the doors off! Do not hesitate!
It is amazing! Fit like a glove. Thank you so much
This is the best and only box you'll ever need to buy if you like serious bass.
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.
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
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
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.
Installed this in my 2016 F-350 Crew Cab. Beautiful fit, sounds great.
I have used this box with both 10" and 12" Kicker Q series and it hits hard. The airspace must be better for the 10". The new seat lift is much better than the previous lift. A++
When I was looking for an under seat solution for my '24 ram 3500 work truck, I found a few options. The ram elite box was a no brainer. I added 2 tropo XL's and a CT 2000.1D and there is NO disappointment. The 2.5" seat lift is tight but gave me the room I needed. I had to switch my amp rack plans a few times as the space behind the seats is limited with the seatbelt mount getting lifted as well. The only advice I have is be patient, good things take time and get good speaker terminals. The people at Fox were very helpful and put out great quality work. Very happy. P.S. I also removed the 40% seat and made a custom perch for my existing JL12W7 and Jl 1000.1D so that with a good DSP has been a nice boost to an otherwise inconspicuous work truck.
Man I got 2 Skar svr 12s and a Skar 1500 and this thing is banging bro! Sounds great looks great!!!!
I started with a Skar box, wasn’t impressed. Then this box was recommended to me and it turned out to be a menace with Infiltrator subs. This box is high quality and holds up with good woofers. My wife thinks it’s obnoxious so that’s how you know it’s amazing. I have 2 kids and the car seat still fits even though the back seat is raised. 10/10 highly recommend for this price!
Came in super fast, and looks and sounds awesome. I def recommend the sundown subs for this enclosure, but overall, amazing build quality and sound.
