Review: Value is best and quality is close to other brands! - Absolutely a needed component for our boat install the bedliner is water resistant and even with a shallow woofer this box was amazing. It fit our poke audio marine sub perfectly. And the best value for the dollar. It looks rugged and has a nice sheen to it. It's pretty heavy I recommend screwing it down with brackets for sure!. Functions better than expected and cheaper than the star box I was lookong at previously

And the best value for the dollar. It looks rugged and has a nice sheen to it. It's pretty heavy I recommend screwing it down with brackets for sure!.

### ⭐⭐⭐⭐⭐ Perfect Box once you seal it! Paired it with a T5-122 Tarantula & a Taramps HD2000.1
*by L***R on November 28, 2025*

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.
