Today I took out my box for my btl's and I think I want to build a wall. For a wall in a car what frequency and port area should I be shooting for? I was thinking something like 14 cubic feet and tuned to 32 hertz with about 300 square inches of port area(for daily driving). I have just ripped out my box that was to my window line and want to do a bigger and badder build but I wanted to hear what other people think before I start. This is going into a Mercury Grand Marquis. I have never built a wall, but I have watched many builds on this forum and any tips appreciated.
Thanks,
Nate
