2007-13 Toyota Tundra Double Cab Sub Box Downfire Dual Ported

­This is the 2007-13 Toyota Tundra Double Cab Sub Box for under the back seat. ­The 2007-13 Toyota Tundra Double Cab trucks are completely limited on space for a stereo system. The only usable space for a subwoofer is under the rear seat and shallow mount subs are a must because of the limited space. Even with shallow subs airspace is limited. This design uses either a single or dual 10” or 12” subs with a total airspace of 1.5cuft but the mounting depth is only 5” with my metal back plates, and only 4 1/4″ with out the metal back plates, so few traditional subs and even certain shallow subs still won’t fit. Most company’s try to save space by using thinner wood which makes a weaker box which is a no-no in my book, better box better bass! I’ve seen this box made and sold using 1/2” MDF with 1/8” wood extension plates and of course it failed and rattled terribly. This box uses every last square inch of available airspace with full 3/4″ construction and the steel backing plate standard on the back of the box to get the most mounting depth possible. My box also is divided for the dual sub versions to get the right amount or airspace for the subs and to also brace the box in the middle better to make it that much stronger. Another thing I did to get a better box design was to get rid of the cut out around the seat belts. By moving the back of the box forward by 4” I am able to use 1 piece of wood instead of 5 which again means a stronger box with less seams to fail.

This is a ported subwoofer box. Ported subwoofer boxes are for customers who want louder, deeper bass with the lower bass more pronounced. Because of the ported design, the bass will not be as tight and punchy as a sealed box, but there is double the bass of a sealed box with the same subs. A sealed subwoofer box has a tight and punchy bass that is more articulate and more true to the music with a more natural sound. If tight, punchy bass is what you want then our sealed box will be what you want.
