Building a speaker box into the bed?

I need help and ideas and tips on how to port my cab i have a 2002 chevy silverado std cab short bed. I eventually wanna put a toneau cover on, so i am curious to know how big i can make the box into the bed. Also what would you suggest i do to make it as clean as possible and making the front wall of the bed look connected? Please help ive been trying to figure this out for a while and finally decided to post. Any pics would be great to so i can get a better idea of what im up against. The only person ive seen with this done is SKIDROW. but i would like to see this on some fullsize chevys his is a nissan. Thanks A.J.
