ok so i have a 2005 GMC Canyon extended cab
the space behind the front bench seat is pretty big for a medium size truck. so i was thinking i want to make a sub box that can double as a seat when necessary for short trips, beer runs, etc.
SO i want to make a sealed box to run straight across the back, that can have two people sit on it without comprimising the structural integrity of the box, and have atleast 2 12" woofers. good idea? bad idea? thoughts?
