7. MDF will ba allright as long as you make sure to saturate every mm with fiberglass resign; Otherwise, The MDF acts like a big smelly sponge. If you plan to replace your seatbase with a box like HH(on the ole tug ), 1step, Slick, and RC did, Marine ply will be the way to go.

What is the advantage to fiberglass resign a sub box. Is it for better sound or to kept it from getting wet and becoming a smell sponge? Would you need to resign one that is under the bow and away from water?
