      I have an 05 extended cab. Before you might think this sub will not fit your truck from the dimensions... I believe the height is listed as wrong. There is only about 8 inches under the back seat and it says 12 or so on here. It fits perfectly, the box is about 8. What's great about this box? The fact that I drive a truck and can have a sub fit perfectly behind me. Also since the box is not ported it provides very clean and clear bass. It really is perfect for a truck cab as you feel like it is all around you and not just right behind you. Because the box is not ported, however, you're not going to be heard coming from 7 blocks away. But obviously if you're in a truck, that is probably not your goal. Overall this is a great box. If you have a truck you really do not need 2 subs. I love the low end and I really only need 1. Go with this box and you'll be very pleased.

      Perfect Fit


      I have a 2003 Chevy Silverado Ext Cab. I only wanted one 12 in my truck but all the boxes that i could find for trucks where the thin square " truck" boxes the ones size fits most type. The dimensions where not what i needed and would have been a awkward fit. This box sounded like it would do the trick. When it arrived i test fitted it in my truck and it fits snug under the rear seat with a little room to spare on the side but over all it fits like it was made for the my truck. As for the sound i have not had the sub hooked up yet but i will update when i do.

      perfect fit!!


      I just installed this enclosure in my 03 gmc 2500 extended cab and it was a perfect fit. sound quality is good and the appearance is great. seat sets down on top of the box perfectly. if you are thinking that you could put your amp on top of the box and still lower the seat, you can't do that. that is the only thing i would change about it other than that it is perfect for someone that only wants to use one side of their truck for speakers and the other side for a storage box.

      Well built box


      The box is nice, seems to be good quality. My only problem with the product is. It was bought to fit under my back seat in my 93 chevy. It is not exactly what kind of fit I had in mind. Its under the back seat but does not slide in all the way. Which leaves it sitting out from under the back seat exactly where I didnt want it. Other than that it will do for now. Box sounds great.

      Not the Best Fit


      The box didn't fit well in my 2010 Silverado Extended cab. The sub was sitting directly on the floor and didn't have any room to move durring bass output. I had to kind of prop it up a with a little wood scrap piece. The box looks awsome and sounds great though.
