QPower Single Triangle Car Audio Ported Subwoofer Box, Fits Most 12-Inch Subwoofers - Deep Bass MDF Enclosure with Bed Liner Finish, Tuned to 54 Hertz, 2.2 Cu Ft Air Space

The QPower 12-Inch Single Sealed Subwoofer Enclosure is an excellent choice for anyone looking to get clean, tight bass from their setup. The box feels solid and well-built, with quality carpeting and a perfect internal seal that really helps the sub perform at its best. It fits most 12” subs snugly, and the sound is deep and punchy without being muddy. Installation was easy, and the compact design makes it great for smaller trunks or under-seat setups. For the price, it’s honestly hard to beat — durable, great sound, and built like a tank. Highly recommend for any car audio upgrade!

Worth the money. Good box

This box is great, but you MUST seal it yourself. I paired it up with a Tarantula T5-122 sub. This sub recommends tuning at 30ish hz but it QUAKES in my single cab Chevy. I’m pushing it with a Taramps HD2000-1ohm amp. I adjusted to amp to respond between the recommended Hz for the sub and the 54Hz that the box is tuned at. I have my gain and boost at 1/3 max and it’s hard to breathe when I hit max volume on my stereo. Perfect setup for less than $500. I haven’t broken in the sub yet so I’ll update this review later. They say 3/4 mdf but it seems more like 5/8ths, if you don’t seal the box it will rattle and crack the Berliner coating. Overall this thing has impressed me. Worth the $$ and with the right sub it POUNDS. Do the research, the T5-122 was the best sub I found in my price range to fit the tune of this box.

Good for the price. As others have mentioned you will need to properly seal it save yourself some time and pickup liquid nails and do it before hand so you don't have to pull your sub out and reinstall like me. Shipping was fast. Couple little scufs here and here but no actual damage to the box or liner coating. All in all it's a good box but you must seal it properly!

I bought one of these boxes a little over a year ago for a 10 inch sub it made a huge difference with that sub one of the better boxes I have ever used so now I bought this one which is pretty much exactly like the one for the 10 except for this one's for a 12 and once again it made me major improvements to the sound quality

Great quality box and shipped very quickly. Wasn’t expecting it til 3 days after Christmas and it delivered on Christmas Eve! Thank you for getting it here so early. That was very fast!!! 5⭐️ service.

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.

Nice build high quality sound

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

recieved said unit with a big ding in the side. GUYS double box your items.. anyways not going to send it back, while fixing this POS it is just a stable piece of sawdust. the only thing that holds this thing together is a spray lining. how this became #1 is a joke. get yourself something that will rock your space .... get a SKAR AR1X12V... solid and double boxed. this unit at #1..... right must be a joke

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
