whats up people. i need a little help and advice. i have an 01 silverado and my plan is to tunnel into the bed so i can put some 15" woofers in the bed. the tunneling isnt an issue, i need some ideas or pics of what to build the box out of and what to use for the best possible protection from the weather. alot of people say this hurts the resale value, but this baby is paid for and is specifically a show ride. any ideas or pics would be greatly appreciated!
