We’ve talked about installing ceiling speakers but didn’t cover much about what’s on “the other side”. You could just stick the wires through a hole in the wall, but that’s not going to offer you the cleanest look. Instead, look into Keystone wall connectors for a clean, modular hookup for any of your wall jack needs.
After installing a standard mounting bracket, you’ll choose a wall plate with 1, 2, 4, or 6 ports. In each of those ports, you can use a variety of jacks, such as ethernet, HDMI, coax, RCA, or speaker wire.
