Hey Ryan, I seem to remember someone had a nice box built in their trunk for their system, was that you? If so how about some pics, I am running a pair of 12's free air right now and I would like to build a box for them like that pic I saw.
Here are a couple that I had on my computer already. My box for my 2 10" subs is behind the board with the grey mesh center. that piece is purely cosmeteic to give the trunk a cleaner look. I will take a pic of the box behind the cover this weekend.
