Bbox 10" Single Sealed / Shallow Mount Subwoofer Enclosure Boxes & Enclosures - Pro Audio Tune - Premium Subwoofer Box Improves Audio Quality, Sound & Bass - Nickel Finish Terminals

The cutout hole was not wide enough at first but after using a Dremel, got the subwoofer to fit perfect. This box fits behind the seat of my single cab Ford ranger so space is not an issue. no air leaks and everything sounds good so far

Bought this to put under the rear seat in my '00 F150 Super Cab, which is mostly does just sticks out a bit. Not a big deal for me because I never have anyone in the back seat. Installed a shallow mount Rockford Fosgate sub and it's a pretty decent sounding package. Obviously it's a small volume sealed box so it's not going to have big booming bass, but for listening to rock it's a great combination, and fills in the bass component of the sound system nicely.The box itself appears well built, the carpet is nicely attached with no flaps or bits hanging loose.My one nitpick item is that there's no wire coming off the terminals inside the box like the competitors have. This is a very minor inconvenience, and like I said a nitpick item, and not enough for me to dock a star from the product rating, just something to be aware of. If you're installing a new system then you more than likely have some extra speaker wire laying around anyway.

This fit under the back seat of my 2018 silverado 1500 crew cab, with about two inches sticking out from under the seat, otherwise fits nicely under the passenger side and you keep the majority of your under seat storage. And it fit with full plastic floor mats. The box is very small and shallow, which is exactly what I was looking for, just be aware of the recommended sealed box size when buying your sub because this box is very small. Also be mindful of your subwoofer xmax if going under a seat because the sub may touch the seat a bit. The quality seems fine, the carpet is starting to peel off a bit now on one of the seems but that's after almost two years of use and pulling it out and back in multiple times for various reasons. But for the price, I think it's definitely worth it if you're working with limited space, without spending four times the price on a custom box.

First off, do not try to put a Sundown 10" SD-4 in this box unless you want to heavily modify it. The opening of their 10" box is 9.125" and the opening required for the 10" SD-4 is 10.94". Okay, fine. Nothing my router can't handle. Next issue was mounting depth. While this is a shallow mount sub, it was about a half inch too tall with the magnet hitting the bottom of the box. Again, nothing a little router work can't handle. I notched a half inch out of the backing board so the magnet sits in it (all sub cooling is with side vents on this model). May have weakened the box but had no choice. Finally, got the sub screwed into the box and ready to try it out. Sounds good from the driver seat, go to the trunk and hear a loud rattle coming from the box. At first I thought the sub had an issue but nope, air was pouring out of the terminal connections with every bass hit. No, the router can't fix this one but a tube of RTV silicone can! Gobbed the silicone all around the cheap plastic terminal port inside the box and now it is air tight finally. So, in conclusion the fitment wasn't their fault, I just want to warn anyone trying to put a SD-4 sub in here what they are in for. The cheap terminals and especially the sealing of them are their fault though. Rest of the box seemed decent quality. For that, 3 stars.

I was impressed like others after reading reviews on this product. The box was shipped quickly, looks to made very well. Since I have 2014 Fiesta ST and didn't want to fill up the back hatch with a large sub-woofer (12") and a single 8 wasn't enough. I went with this model and installed the MB Quart 10" and it fits under the hatch tray perfect. As with any speaker there is approximately 40 hours of break in but it did hit pretty good with only a 150 watt amp running at 2 ohms.I tried at first with no poly fill, then week later added some and that improved the low end and its been over 40 hours and it even works better, shakes my cabin very well and hits pretty good. If you on a budget and lacking space for sub this is a great whey to go for under $100 for MB Quart sub and box.

Massive air leak from the terminal which is very different than the one pictured. Put in a gasket only to find out the terminal is of poor design and not suited for a "Sealed" enclosure as it leaking air from the connections. Replaced with a suitable terminal only to find a large leak in the joints of the enclosure. This is really bad as I used a whole can of rubberized undercoat spray on the interior prior to installing the sub. After about an hour of trying to get the enclosure sealed I was able to reduce the leaks to a somewhat acceptable level and was able to double my bass output. If you don't have the tools to make this enclosure work you are wasting your money. For me it was a monumental waste of time.

Great box. Fits perfectly under the backseat of my tundra double cab.

Sub box is as claimed - the mounting depth is correct - some boxes have weird shapes or cutouts to claim a deeper depth, but this one does not. The construction is very solid and sturdy, and the terminals are the quicker, easier push-button cylinder style (not threaded). I fit a JL Audio 10TW1-4 into the box and it fit perfectly. Well worth the $40 price tag.
