How close can I run speaker wire next to electrical wire? Built a new home and ran speaker wire for surrounds. Haven't used them yet but now am ready, however, I've now decided I need to move the initial location so I will be extending the line . Problem is I will be running close to an electrical line. I've read somewhere not to run parallel close to the electrical wire and cross at a ninety degree angle. Well I don't have an option but to run parallel with the wire. I can run inside the frame of a door providing a gap of some 2-4 inches between the door frame and the stud(need to look at the video of the wiring before sheetrock to make sure) So bottom line I must run a speaker wire parallel to an electrical wire but if I'm between a stud and maybe a door frame am I far enough away to avoid problems. Only other option is to use original location and change speaker choices.
