I purchased a home with a media room that was prewired for surround sound. One end of the wires is in a low voltage single gang box, the other ends terminate somewhere in the corners of the room. There are some telltale plaster spots that have been painted over, but I would like to confirm the wire location before punching into the drywall.
What do you recommend for locating the wires? Infrared? Tone generator? Something else?
