Q Power QBASS Dual 12 Inch Heavy Duty MDF Material Car Audio Subwoofer Enclosure Boxes with Shared Slot Port Vent and Dual Chamber Design, Charcoal

As described. Looks good and decent price.

As a professional installer, I hope some will read this review and get more a more accurate idea about this box. With all my experience, of course I know better than to even think about messing around getting a stupid prefab box. However, I am reccomending this thing, and here is why.You people first need to know that when you buy a prefab box like this one, there are no screws or anything holding the wood together except wood glue. OF COURSE your 2 12 inch subs will eventually rattle this thing apart. No duh. However, the reason why I bought this box was the price. I was fully aware that this box wouldnt last a week with the 12 inch subs installed hitting at max power and volume. With that said, for 52 bucks, you have a fully carpeted and assembled enclosure. Instead of going to home depot or somewhere to spend roughly the same amount of money on MDF wood, then spending time to measure out, cut, glue, and assemble a box of your own, all the work has been done for you....well...most of the work...The same day I ordered this box, I went to home deopt and picked up a couple tubes of liquid nails, some caulk, and some deck screws. For about 10 to 15 bucks extra, I was able to turn this box into exactly what I needed it to be for my system on a budget. I received the box and then began my extra prepping. I checked all of the walls and joints to see if any came entirely loose, and had to actually reglue a few things with the liquid nails. Then I went through and did a complete seal with the caulk, since the box didnt come with that much to begin with, and I wanted this thing to be rock solid. I pre drilled a bunch of holes for the deck screws, and then screwed all of the joints together. I used liquid nails and caulk for the terminal cups as well, since those were on the cheaper side, but now this box has been bumping solid for over a year with no issues at all. No rattles, no leaks, just clean and low bass. I have 2 12 polk audio db subs that are rated for about 300 watts rms a piece, wired to 1 omh being powered by a 600 watt rms amp. These things are seriously so insane for a budget system.Long story short, if you know what youre doing, then spend 15 bucks more and with a little work you will have a really nice and solid enclosure for a super cheap price. No it wont be exactly tuned specifically for frequency, displacement, or anything like that, and its a little thinner than 3/4 inch mdf wood, but for the price its perfect. Don't be silly and think that youre buying a cheap and solid box on amazon for 50 bucks and youre not going to have issues. Of course it will need work, and normally I would NEVER recommend a prefabricated box to anyone. But for the price and with some extra work, its a great starter box for someone with a budget wanting to get into car audio. If you dont have any clue on what youre doing then go have someone else build you a box. Hope this helps!

Got a cheaper box than what is in the pictures the port doesn't curve like the one in the picture would of been nice to get was was pictured for better tuned frequency guess for the price it will be OK but would of paid more for the one in the pic

I see all kinds of bad reviews on here, my advice is try it for yourself!. There’s bad reviews on everything. Mine came in perfect condition it’s exactly what it looks like in the provided picture and it seems to be good quality. I have 2. 2,000 watt subs going through it with a 2,500 watt amp and it slams. Doesn’t shake or rattle at all. I have nothing bad to say about them. Definitely good for the money. That’s just my personal opinion 🤷

I'm sure there are some custom boxes you can buy and some super expensive prefabs but in terms of value for money, you can't get any better than this. It gets the job done and bumps harder than anything sealed. Even with my cheap Skar subs I'm impressed. Looking forward to putting some real subs in this box! Seems like it can take it. Bumps hard!

Incredible quality for the price

Cracked the box in the first 30 secs of play time not good for high quality subs at all lol

I don't know who the whiners are about this this thing is very heavy and very well made it bumps so hard it actually pulled the wire out of my fuse box in the trunk of my charger so pain no mind can those people saying is cheaply made its far from it
