this is whats going thru my crazy little mind right now. i have this idea of building a new housing for my champ using either heavy birdseye maple or bubina. i want to make the new speaker cut out so that it will hold a 12". i plan on making the housing taller and if needed wider. does anyone have any dimensions from there champs that came stock with a 12". what ohms should i use? i kinda what the wood alittle beefy too so i was thinking 5/8" or something. PLEASE HELP ME OUT!
