Well i got my 12" exs dual 2 ohm installed, this is not a review. All I have to say is DDAAMMNN!! Not that its extremely loud or anything, not broken in yet though, but this thing will hit all the low stuff. My question is, as of now the sound only comes out the front of the box(downfiring in an f150 console box see link) http://www.caraudiocentral.net/forums/s ... php?t=3505
anyway, the bass is not focused in the truck, if that makes sense. for example.... the further you walk away from my truck the louder it gets!! weird anyway, the acoustics are not necessarily what you want for this type of setup. so, do you guys think maybe I should vent some of the bass out of the sides? I thought of tightening the hole that is firing forward by shaping it with some bondo, then cutting out some vents on the sides. as a side note, this sub has some major excursion!!! my box was actually coming off the floor before i attached it tonight. not like a 1/4" or anything but it was f'in moving!!

So you're saying you don't like it that much? :-P

My Brahma was similar to that when it was in my van. It seemed to get louder the further away you were, granted you were in an open area.

ok, lower frequencies have longer wavelengths, so it takes longer distances (by literally feet) to mature a full wave as you drop in freq.
Your sub may have a low Fs, and be tuned low as well, so it's peaking at a long wavelength in a horridly small cabin (pickups.. one of the drawbacks)
Try sound deadening the hell out of the floor, to retain more energy inside the cabin, or try going from ported to sealed.
Another drawback to trucks is they tnd to get really bad "trunk bass" where the sound gets a lot louder with the windows cracked or down.
This is best fixed really by finding a way to couple outside air to cabin air by venting to outside in the car cabin somewhere.. like the firewall, or rear wall by the bed, where it won't be seen, and you can filter out the elements from outside.
