Help with Sub Woofer Box
 

I have a 1969 c-10 Long Bed and am thinking about building a bos for some sub woofers. i took some measurements and it is about 55" long and 14" long with 5-7 inches tall and a 2 inch raised bump in the middle. if some could help with plans or had a site that sold boxes that would help.. i am planning on user kicker compvts because they are compact and will fit better. tinking 8 or ten inch.
