Specs -

22" tall

44" wide

22" deep

Double baffled

Subs and port facing rear. Make sure you install the box so when looking into your trunk, the port is on the right just how it is in the pic below.

Port area - 20.5" x 5" = 102.5" Tuned to 33Hz @ 8.0 cubic ft NET after minor bracing shown below.

Port is attached to back of second baffle. The port wall depth is 14.75" This allows a 5" wide opening from the end of the wall to the back wall of the box. This is important as you must keep the opening 5" wide.

The bracing can be all thread(not the vertical runs obviously), or wooden dowels. Diameter really isn't too important, anywhere between 1-2" is fine.

The bracing shown gives u an idea of how to do it. Make sure that when u do run the bracing that you TRY to get them all next to each other perpendicularly then tie them together or physically join them together by running them into each other, etc...
