## Customer Reviews

### ⭐⭐⭐ 







  
  
    Could be built better.
  

*by A***C on Reviewed in the United States on May 13, 2017*

Really shallow, very limited on selection of shallow mount subwoofer that can be used. I mounted a DS18 shallow mount that barely fit in there. The box has too much wasted space for the standing base. It uses about 2 inches that could've been used for inner space. Over all it fits perfectly under my 2016 GMC sierra Double cab and the subwoofer sounds ok. Wish they made a down firing box.

### ⭐⭐⭐⭐ 







  
  
    Great
  

*by R***Z on Reviewed in the United States on August 17, 2021*

Great and simple, fit perfect. Sounds great for what it was intended

### ⭐⭐⭐ 







  
  
    looks good.
  

*by T***H on Reviewed in the United States on March 17, 2016*

Box looked good but was not sealed. Half was sealed and the other half allowed air to escape .
