Earlier this year i was planning on getting an alpine type-R 12" but i decided not to install any system. and i was making my own box and now its g2g but just don't wanna throw away.
dimension is 14.5"x14.5"x11" .85 cubic ft., front double stacked, 3/4" MDF
this box is INCOMPLETE, BUT just one side need to be done. i'll give u same screws and the leftover glue that should be enough to finish the box. u will only need a screwdriver or drill for easier finish, sand paper and file. im not a professional and ths box is not perfectly rectangular but pretty close.
i live in denton, tx 76210, come get it for $10. all the materials costed me about $25. i'll upload some pix soon
