The type of copper and how thick it is, the jacket protecting the copper, the distance it's run — all of these impact how your system will perform. Make sure you're choosing wire that is the proper material and has a thick enough gauge for the location and distance it will be run.There are also different wire ratings that dictate what kind of wires are run within different areas of a house.

Once your mounting location is ready, ensure your wire is ready to be connected. Test your speaker after connecting the wire by playing something through it. Once you get it to work, hang or attach the speaker depending on the method being used.
