heres the box i am hopefully plan on building as soon as i can get an okay from someone who knows what there doing haha. i plan on putting it in the back of my 2007 dodge caliber. i have a total of 7.55 cubic feet. the port is 24" X 2" X 6" long. *hopefully* tuned to 33hz. i am new at this, so just need some help on everything. i had something similer to this posted up, but it changed to much *thanks to you guys* that i thought i would start a new thread. let me know what you guys think, if you can give me the "OK" to start the build.
