Homerun = central location where all whole house equiptment and wire begin...
From a homerun , wire every room with CAT5, digital coax, and 16/4 speakerwire where ever a computer or tv may go. From the same home run, run CAT5 and 16/4 speaker wire to every location a volume control or access pad may go. From each control location, run CAT5 and 16/4 to the locations that inwall/ceiling speakers may go.
