This box is built very well! I am pretty happy with the quality. I have a 2014 Silverado 3500. I'm their website it states that 2014+ trucks needed the seat lift, I was hoping I wouldn't need to install the seat lift that this box comes with. I ended up installing it after I put the box under the rear seat. I could feel the cone extensions through the seat, which made it pretty uncomfortable to sit back there. With the seat lift, it's better! You can still kinda feel it under there. It's still comfortable enough to sit back there, though! I installed 2 CT Sounds TropoXL10's with a Skar 3500.1 amp. I wish I would've bought the 12" box instead of the 10, but I didn't realize there was a 12" version at the time. I'm pretty happy but also a little disappointed with the amount of bass this box produces. I'm thinking that once the subs get broken in, they will hit a good amount harder. Overall, I'm pretty happy with this setup! The audio in my truck has never sounded better!
