it matters how big the port is, but i calculated that to be over 10 cubes gross, when net after port and sub displacement you would probably want around 4

too big is what your saying? this is what the guy that is selling me the subwoofer said

"This box gets real loud in pickups.
The EXTERIOR measurements are: Width=36.75" Depth=24" Height=24"
INTERIOR dimensions are: Width=34.5" Depth=22.5" Height=22.5"

Double the thickness of the end panel of the box you want the subs and port installed in.

The port and sub will fire toward the passenger side of the vehicle.

The port will be 5-5/8" wide and 22.5" tall. Measured inside port walls.

Use one box side wall as the outer port wall. Make the inner port wall 16" long from the OUTER face of the end panel. Bevel or round off the ends of the port walls

Brace the box with 1"x3" slats both vert and horz in the center of the box.

Mount the sub =distance between the INNER port wall and the side of the box.

Your box will be 8 cubic feet net after port and sub displacement.

The sub and port will fire to the passenger side of the vehicle. For best results the port should be 4-8"from the passenger side door. Move the box within this area to find "sweet spot.

Your box will be tuned to 40 HZ but the sub will play well below box tuning. You will hit the lows."

i dont know much about what size boxes those subs like so hes probably right, but generally 15"s need around 4-5 cubes. remember that is a very general statement though. 8^3 is like a box for an 18"
