His.

I'll start playing with a few things for yours in a bit. There are some good ideas above. Dereks box is already built, and a direct drop in if you can get the subs to fit.

Less' idea might be louder than dereks box, hard to say without testing. Dereks was built for daily lows. Why not try Less' way first? It's something you can do almost right away, then go on from there.

i think if you have any subs facing up, fire the port back or to the side

i had a box sub up port forward and it wasnt very loud, flipped it so sub up and port back was an easy 2-3 times louder!

That was because you were tuned so low, turning the box lengthened the wave length. There's a thousand variables... I'd try it Less' way first. Port and 2 subs forward, 2 subs up. Otherwise a design like Dereks will get everything into the cab.

This is a design like Dereks only made for your subs and vehicle. It's tuned a little higher, and should get you closer to your goals. PM me your email address and I'll send you the Sketchup drawing.

Just found it, I'll send it to you right now.

Edit! Seems yahoo isn't letting me attach it again. I'll have to try something else, it might take a bit.

Edit 2 - Sent it, now I just hope you received it, lol.
