I bought a new house which was prewired for surround sound. Right now, there are wires that are covered with outlet plates. Can anyone help me with how I can connect those wires with my speakers and receiver?
as long as one of the wires in the pair has unique markings (and it should) and you know where in the walls the wires live (outlet plates) there is no reason you couldn't figure out what it what by trial and error.
that said, what kind of professional installer doesn't label wires at the home run and at multiple wire drops? i mean, what moron can't figure out the painfully obvious fact that without labels a dozen wires in a bundle at the home run is going to be a major pita for the homeowner?
after they ran the wires for our new home i called the installer and asked them to come back and label all these wires - a few dozen speaker/coax/rj45. he had the nerve to ask me "why?"
In many spec homes not labeling is intentional. The company keeps a wire map but they want to make it as difficult as possible for anyone else. On the other hand install the speakers and use a battery to identify what wire goes to which speaker. We call this a pop-pop test. Use a AAA or D battery not the battery in your cordless drill.
