Re: GURU's---Will this sub box work?
you prolly don't need 3/4" and 1" mdf. it will cost more than getting 1 sheet of one or the other. i think i have your box pictured in my head(a drawing would have been nice) but i'm lost as to why you would have them on a 4" platform. that just seems to be a waste of wood and space. it would also be very helpful to know what kind of vehicle this is going into. maybe you should stick with know working enclosures to each his own though.
