*** PART I – GATHERING SUPPLIES & DESIGN CHECK ***
Sammy Sandbag wrote a great "How To" for a Subwoofer Box that fits perfectly under the rear seats of his Titan. The only problem is: Sammy has a Crew Cab with a lot more space under his rear seats than those of us with King Cabs. However, Sammy’s post showed me that I could make my own since the materials are readily available, and once acquired, the box is simple to make and costs less than half as much as a custom box from an audio store. And it looks & fits better!
I started by measuring the volume under the rear 40% seat. I then drew this volume in SolidWorks (CAD program) and shelled it out with ¾” thick walls, simulating a box made with ¾” MDF. I played with the dimensions until I had an interior volume of approximately 0.75 cubic feet, which is what my 10” subwoofer manufacture recommends (RF). I then made a cardboard mockup of the box for a test fit. I noted areas that interfered, and made dimensional changes. I continued doing that until the mockup (plus space for the speaker & grill) would fit.
Once I had a design that would fit, I cut it up into 6 separate parts, using a combination of ½” and ¾” thick pieces of material. The Home Depot I went to had precut pieces of MDF, which is what I needed. Since ½” MDF was available, I used it to increase the internal volume of my box, but only used it in areas where the screws would only go normal to the face box, not through an edge. I took the 6 separate parts and made a complete SolidWorks assembly out of them using to the cut dimensions of each part, making sure all the pieces would fit together and that the complete solid model assembly would have the correct final dimensions and would fit under the seat, like my mockup.
