all of what stuff? Wood, wiring, screws? get teh wiring from some place like knukonceptz and the wood and carpet and everythign else from HD or lowes, which ever is cheapest. Build the box with mdf and have the plans made by someone for very cheap, unless you know how to build a box yourself. Do you want to go sealed or ported? Single sub or dual? 15" sub(s)? how much space do you want left.I could probally do it myself but where would I get all of the stuff to do it? Crutchfield or is there someplace better?
