Wall jacks in the garage for speakers/5.1 sound and HDMI. There's a matching set of jacks on the wall behind the home theater gear cabinet in the living room. This arrangement allows me to move my front speakers (L C R) and subwoofer into the garage and quickly connect them to the home theater gear in the living room. All of my gear (A/V receiver, Blu-ray player, etc.) is controlled by RF remote, which allows me to take the remote to the garage and still control the gear in the living room.
