    • This box rocks.

Qbomb has done it again. If you are looking for something cheap and really high quality this is a wonderful option. This thing sounds amazing and has a great frequency range. I am running a sundown e8 and it plays lows like you wouldn’t believe. I definitely recommend getting this box if you are on a budget. ... show more

The media could not be loaded. I decided to purchase this box coupled with a 900 watt RMS Skar Audio ZVX-8 D4 8" (powered at 2 ohm ~800 watt amp) sub to replace my 2x 12" setup to save some trunk space. It sounds AMAZING! There's one down side to this box that customers should be aware of: the subwoofer cutout does not universally fit all 8" subwoofers. The ZVX-8 was a little bit bigger than the hole cutout, I had to shave down about ~0.5 of an inch to get it to fit. This box was probably meant for some lower powered 8" subwoofers. So buyer beware: measure before you buy, unless you're comfortable with trimming off some wood. ... show more

    • Great box. Good price!

This box is PERFECT fit and sound for my sundown audio 8in subwoofer. It lets my sub hit them lows I was looking for. While still being punchy for a porter enclosure. Will DEFINATELY recommend. Liked it so much I ordered another one already!

    • Wrong tuning FQ, READ ALL REVIEWS!!!!

Review Image by SM SM
As many others have mentioned the tuning on this box is not 34hz. It is in fact much higher. At first I was very happy to have a space saving setup for my new car compared to my old setup that is 3cu ft, truly tuned @ 32hz. This box sounds terrible at low frequency ranges. I am very disappointed with that. Also being the fact I cannot return it I now am "stuck" with a product I do not desire AT ALL! Yes, it can be fixed with modification and materials, but that is not the point. False representation in the description will lead to more dissatisfied customers. I since have put my old setup in until I get a replacement for this box or modify as the wrong tuning makes my Skar EVL-8 sound terrible. Please, please ,please fix the tuning range and read the reviews! ... show more
