Qpower Single 12" Vented Ported Car Subwoofer Sub Box Enclosure, QBOMB12VL - Single Cab Bass Woofer Speaker Box System for Vehicle or Truck Audio

Great sounding box for 1 12". It has some flex to it but it didn't break. I hit it with liquid nails anyway as a precaution. I have a sub in it that's a clone of a Sundown SA classic ( its an Audio Legion S2512) and it sounds great. Low but still very musical. So much so that I chose to run it in my home theater. ( I have a big home theater, very powerful). it's tuned lower than the specs say, like 34hz if memory serves and not alot of port noise either, that's another reason I used it in my home theater setup. I'd buy it again but I wouldn't put anything too big in it. Sundown sa classic or lower. The Resilient Sounds Onyx 12" in the picture has nothing to do with the review, its just too heavy to move out of the way so deal with it, 😆. I would never use this box for something like that monster. BTW, the liner on this box is TOUGH! It's not junk liner. I was surprised how tough it is.

OK. So I already own the dual 12in enclosure so I knew the build quality would be great. My concern was the port. Now I already said the build quality is great, as in its solid, sturdy, with that coating acting as a shield from the weather as well (humidity and wet weather I mean) it's a great build. But it isn't exactly ported like a high end enclosure is. It's close, as you see in my photos, they have the port at the end of a long box. And that acts as an enhancer for the bass. Well it's supposed to. Its supposed to be more obstructed along that long box hole before the port. Kinda like a tight maze of wood all down that hole. That makes it almost like the box is sealed because the air has so much to get thru before the opening, and this enhances the bass even more. Don't get me wrong. This box makes my Rockford P3D4 12 SLAMM. But with that port, it doesn't produce the deeper lines of bass. Those low rumbles So as you can see in my photos, I sealed my dual 12 enclosure and it made it sound extremely better and made it be able to produce those really low bass lines. So I am probably going to seal up the port on this box as well. I've always liked sealed enclosures better man. They just sound much better to me. But to each his own man. Regardless, this box is awesome! And I highly recommend it! If you only want one subwoofer in your vehicle, this is the box you want for it. It seriously sounds like I have two subwoofers in my car

Its got a hard pounding bass even with a low end speaker BUT very minimal low hz frequency in my opinion… tough box hard to crack

This thing works as it should.It's the perfect airspace for my specific subwoofer. Nice and tough exterior it does have a little bit of a smell to it. So expect that. I have no complaints. I did see some of the reviews saying that some of the edges were coming apart. So to mitigate that I threw in some small wood nails to help support the box from falling apart. But i've had no issues after putting in wood nails. I'm pushing about four or five hundred watts to it.And I do notice a little bit of a flex in the wood.The three quarter inch does not go all the way around the box.I believe it's a half inch in some spots.

Two of the boards are separated a little bit and showing bare wood, right on the long edge of the box. Structurally it hasn’t affected anything, it’s just a noticeable “crack” that would bother anybody who is getting it for the looks. As far as doing it’s job, the box performs. Fits my type r 12 and almost doubled the sound compared to my old sealed box. People can’t believe it’s only one sub! If you want low lows this may not be for you, but I enjoy my bass in the high 30-low 40 hz range and this enclosure is spot on. Price is about average, not too bad but not the cheapest either. Minus one star because of the crack, otherwise 5 star product for sure.

Like a few of the other reviewers on here, I have a single 12” Rockford Fosgate Punch P3D4 (dual 4ohm voice coils) wired to 2ohms. I have a Kenwood KAC-9106D bridged to 2 ohms for 1,000 watts RMS, 2,000 watts MAX that pushes it well. I’ve been into car audio for the better part of 25 years and have had about every configuration you can think of, from stock equipment to thousands of watts being fed to 15” and 18” subs which break windshields. I wasn’t expecting the world out of my current little system but want it to be the best it can be. I had my 12” Fosgate in a generic pre-fab ported box that sounded okay, but I figured it wouldn’t hurt to pick up a box that had the precise air volume that my sub called for, (1.79 cf) so I grabbed the Q-Bomb single 12” version 1.8 cf. If you are even thinking about picking up this box and are reading this review looking for advice, BUY THE BOX. This thing is bananas. My bass is twice as loud as my old box and I haven’t touched my amp settings. All I did was change the box. These things are ridiculously sturdy, clean looking and sounding and unequivocally SLAM. Hard. This is easily the best box I’ve ever had. I’d pay twice the price for these results all day long. I’m extremely happy and completely astonished with it. It’s freaking loud, I’m telling you. Especially if you have a Fosgate P3 or anything with the same airspace requirements. Get it. Do it. You’ll LOVE it.

This box is pretty good. The 12” hole was a tight fit but it seals once you screw in the sub. Overall it’s pretty good and looks good too.

Doesn’t sound too good. Just my personal opinion. Built tough and sturdy but just not a good fit for me

Shipping is super fast and they handle it very well. Thank you

Perfect little box sounds fantastic with and 800rms deaf bonce 12 in it. Running the audiozerone 1k rms amp. Fit Perfect in between my truck seats in my single cab

This box is the best pre fab ive tested by far my type r is awesome in that box! The terminal is kinda cheap only downside but can be fix easy

This box is really good if your on a budget and sounds just as good as the more expensive ones quality box

wow i used a sealed box with my alpine type r sub once i installed it and use this box , i have 2-4x the base , verry solid unit !
