Obama has a law he's trying to pass right now, trying to ban Leo for being a threat to children everywhere.



EDIT: Not in a JP kind of way.

I thought I was going to die from all the jizz filling my ears.

Mine is a turd sealed up. One window down 28hz down is nasty, but 29hz and up both windows down and she gets crazy. 35hz + I can open both doors and play full tilt.

i lose like crazy windows down, but.. Drivers port and the wall is far from sealed off. I hope once i seal off it will gain, but who knows right?

I gain around 6+ db just by opening the door or both windows down versus sealed. Great for demoing which is what mines built for. Seems like the driver side port guys do very well sealed up.

The window or door open will act as another port, and make your cabin behave like the front chamber of a bandpass box. More often than not it gains, but sometimes it looses or makes no difference at all. From what I've seen it's a most dramatic gain in pickup trucks. I've been told that boxes with smaller ports gain more when you open a window but I haven't really done much testing since everything up this way is sealed at the dash.

Really if you're competing you need to own a meter and test for yourself unless you know somebody that has owned the identical vehicle and done all the testing already.
