YEAH! thats what i did i went threw the same hole u r talking about i bet! Sadly i did cause damage when installing the wiring :{ i tried covering the wires under the side plastics on the inside of the car. and on the drivers front the 3rd screw away from the door "by the pontiac sill" i cracked "not off but almost" a peice of plastic that i hopefully want to mend back together! "the screw was stripped so i tried lifting it up and stuffing the remote wire and rca cables underneath it
