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.

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!!

Soooo..... DOESNT actually fit my 2014 Sierra slt, even though it says it does. It rides the hump so the seats won’t sit even close to flat. Tried to contact the company cause I have an appointment to have them installed in a week and they were useless, they were like “oh well contact Amazon” even though they DO offer one that DOES fit. Check your floor, look at the shape and buy it that way and save the over and over returns
