Galen got another good video of my jeep playing at the Ruckus show. Since the Sundown show, I've messed with the box quite a bit, I cut the port about 40% shorter and made the box 2.5 cubes smaller. It lost a little down in the low 30s and I think some sealed up but up in the 35-43hz I'm pretty sure its still a 58 with a window down. Haven't done any testing, this is just my ear-o-meter.
It's better to keep your mouth shut and give the impression that you're stupid, than to open it, and remove all doubt.
Mistakes are how you learn; try not to learn too much at any one time.
