DUH!!
Get 2 rolls of duck tape! You first put 1 roll in the box, AND THAN tape up the box!! But make shure the wires from the back of the box are touching the duck tape. THAN, you are good to go! Hope this helps!!
P.S. For the people that are going crazy about me calling it Duck Tape, i'm sorry.

I know it is called Duct tape, but i like duck better...
