    heres a useful site. you type in the measurements and it calculates box volume and gives you the lenghts of how to cut your wood. good luck. remember to use 3/4" mdf wood ok.

    Someone should make a master Subwoofer box thread and link some of these on there then we can make it a sticky. Seems to be what a lot of people are looking for, make a better title though with something like "Build subwoofer box for Silverado".

    There are so many types of boxes you can build in a truck. ZFrom fiberglass to wood to plastic if you like. Just Google it. under seats,front kicks, Center, Just check it out and build a box to spec for that sub. Also get an amp that will do the job right.. Remember A GOOD amp is about $1.00 per watt....Your NOT going to get a 750 watt amp for $179.99.....
