Back in early january some guy posted a thread with a killer free and easy box build program via link.The program folder i copied from the thread was Free Ported Subwoofer Plans brought to you by decaf De Car Audio Forum_files. It was easy to use all you had 2 do was type in the subs spec such as (vas), (Fs), etc and the programs build the box automatically, if anyone can please help me find the thread or the program.
