The box turned out great. Build quality exceeded my expectations. Lots of internal bracing and the coating was applied well. I have 3 Hertz MPS250 shallow 10s in there and it slams. Took one star because I had to go grab some longer bolts to get the amp rack mounted to the back wall. Additionally, by the specs, my subs should have fit perfectly but the cutouts were coated with the bed liner and I had to remove that. I also added more weatherstripping between the two halves of the box. I cnc'd a block off plate for the 4th hole and sealed it off. I would recommend this box for a 3rd gen Tundra if you want max airspace.
