Ok once I have found the resonant freq of the cabin of my truck (I am doing the wall with 2 woofers) I need to know how to calculate the box sizes, and port size? (I have made a few ported and sealed boxes before, but only the factory recommended boxes for little systems. ) I have been told to use a box program, but I’m not sure if I trust them 100%, especially making a big box for a wall like that! If anyone has done this before please let me know how. I’m going to build it during the winter so I have some time to experiment on this, but would like to start right away! Please let me know how to do this? Or if a certain box program can be reliable?

Thanks guys, and gals!

Well there's this program that seems to be pretty good.. It's called" Bassbox 6 pro". It has different designs you can use and tells you just about everything. so maybe look into that.. it's just a suggestion.good luck..
