Here's an awesome tool, compliments to Rockford Fosgate, to help anyone who is thinking of making their own sub box. All you need to do is pick out any of the 4 designs, unit of measure, thickness of the wood you're planning to use, plug in the dimensions, and click the "calculate" button
oh yeah, you'll also need to know the required air space for your intended woofers too
