I am studding out my new games room and I also plan to install a home cinema/projector. I don't want to have a poxy sound system & I want everything to be tidy, so I am thinking of installing speaker cables in the walls. Can I do this, and what equipment do I need? Any recommendations for suitable cable and how to terminate it? Can I terminate at some kind of faceplate/socket and plug an amp/stereo (etc) into the wall? Any web links to suitable kit?
