This is by far the best enclosure that you can get for this truck.
Under seat boxes can't come close to the performance you get from this enclosure and a good quality high powered sub.
Under seat boxes have very little air volume and require shallow, low powered subs and they are too close to the seat bottom. When someone sits on the seat the metal springs will crush the sub causing damage.
On the other hand our enclosure's baffle is 1.75" from the floor and you can put a 8" deep sub.
There is no need to worry about lack of airspace either. Ours has plenty!
