  • Good box
Fits perfect in a 2014 Chevy Silverado, it’s very sturdy. I believe the sound quality would be better if the subs were facing up but still sounds good down facing.

  • Stinks!!!
Make sure you're ready to use this product asap so you know what you're getting. Wasn't ready to use this as soon as it was bought. Put it in the vehicle and it STINKS like musty feet. Seller doesn't stand behind product and advised me to sell it elsewhere as it has gone behind the return date! Not happy at all. 200 dollars for a box that I will not be using bc I can't bare the smell!! ... show more

  • Works well
Good box for under you back seat. I had to raise my seats and add spacers to the box as my subs were firing into the ground. Once the spacers were in the sound was nice.
