I just got done enclosing my theater area from the rest of the recroom/bar area. I just ran some coax within the walls to the locations I wanted with the normal cable type wire ends, then found some modular plates at MENARDS (for Peter) and snap in connectors with F-Conn (Cable) on one end, and RCA on the other.
