I got this aftermarket premade subwoofer box and subs from a coworker for free. I quickly tested it out and it sounded better than the 12" sealed box I had just sitting under the helm. It looked to be a tight fit and thought Id give it a try. I have basic wood working tools. Jig saw, sand paper, square, etc. I borrowed an electric handheld router, 45* bit and straight template bit.
My basic goals were:
1. Hide the ports and cover up the box entirely
2. Have as much leg room as I possibly can
3. Come up with a finished layout that matched the rest of the interior
3. Keep it simple
