any sites on building a ported enclosure

well i kinda need to know if i can just glue 3/4 mdf on top of another peice of 3/4 mdf to make it thicker will that be strong enough that i wont need to put any bracing inside of the box??i am gonna get a 15" brahma thats why was wondering about the bracing

and and i was thinkin about makin all the box wooden except where the sub goes, i wanted to fiberglass that part. can i fiberglass it onto the wooden box?? and can i put ports in the fiberglass??

and

but yeah the tutorial would help alot so if u dont mind can please do it

yeah thats a good idea so if anyone has a design that would work for a 15" brahma hook me up with it

my post has to be aleast 10 characters so i had to type something but i want the box tuned at 30hz
