Ok I am new to working on boats and I am much more at ease working with metal but need to build a new bulkhead and some speaker boxes for my 78 hondo mini cruiser. Can you use just any plywood material or do I have to get something special. I have never built a speaker box either but shouldnt be to hard. Any advice would be helpful. I figured I could use regular 3/4 ply for the bulkead and mdf for the speaker boxes and resin the hell out of them. Any other ideas?
Thanks
Kyle
