I have an F-150 regular cab, I took out the rear window. I built a ported enclosure for my Xmax 15's (2). The box if I remember correctly is like 2.5 cube per side 2 ports 4" pvc x 11.25" in length. I fiber glassed the inside of the box and the outside as well and the baffle is 2 ply thick of 3/4" mdf. It sounds good and gets pretty loud but some bass freq. seem to be a bit sloppy on some sounds. I am driving them with the old pc1400 that has the same specs as the pc1800 (I have no idea why they did that). I am not sure if it sounds like that because my voltage drops so much when it is cranked or if the box was built badly or poorly designed.

i wrote it down at home with all the numbers i think it was like 47 I am at work and I cannot remember I will bring it with me tomorrow. I figured that the resonant freq of the truck had to be somewhere around 90 hertz so I went like half that.
