I am looking to build a new box in my colorado for 4 12in. L5s. i am gonna be taking the backseat out this weekend. The box limits are 50 wide x 20 tall x 20 deep. im wanting to tune around 40hz(i know its high, but i want it tuned high so i can compete a lil and then still have some good daily bump). how should i do the port and stuff? any one got any good box designs? this will be going into a 07 colorado crew cab

I would tune it between 34-38 if it were me.
Beyond that, search for box designs

Heres one I built for a forum member. I can design you one if you give me your MAX parameters. This one was built to kickers specs.
