I have been asked by a good friend to help make his bonus room upstairs into a theater. This is new construction and they are still in the process of framing. The room is 22' x 14' with the back third of the ceiling being sloped with the roof. I know a bit about the electronics side of what needs to be done but the construction side of it is foreign to me. I know the codes on low voltage are fairly slack but what I'm not sure of is how strict they are on where you can drill holes and attach wiring and where you can't. A majority of the 7.1 wiring, including the HDMI cable, will run to the attic and then to their respective locations. Can I just drill a large hole in the top of the wall behind the entertainment cabinet to bring all the cables to the attic? How would you recommend fastening the cables while making the runs?
These are probably very amateur questions but I just want to make sure it is done right and doesn't cause any problems with the builder and/or inspector.
