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

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

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!

Definitely makes a difference with those big magnetic heavy subs

Combined with a Rockford punch 3 wired at 2 ohms it hits so hard it's unbearable after one song better hope you have a bass knob unless u wanna say goodbye to your ear drums and your dashboard at the same time
