Help running power wire

Whats the best place to run a power wire from battery to amp for an '04 chevy silverado? im tryin to not drill any holes?  

i'm not sure about that body style, but you'll be much better off drilling a hole in the floorpan and coming up through the floor, just get a rubber gusset and you have no problems with leaking or metal cutting into your wire.  Just my opinion.

rubber grommet

that's what i was looking for!!  grommet.  thanks, cheeks
