All of my home theater components are in an under-stair closet that shares a wall with the back of my living room.
I already plan to run audio to the subwoofer in the living room, with a nice cover plate, etc., but I'd also like to power the subwoofer using the switched outlet on the back of my receiver/amplifier, so I'm not powering it 24/7.
Running an extension cord directly through a bare hole in the wall seems messy, is there a way to properly create a switched outlet on one side of a wall with a power cord on the other? How would I properly label it?
