Greetings everyone!\n\nI consider myself to be a complete newbie when it comes to home audio. We recently purchased and home and moved in and during the buying process we discovered there were speakers that were built into the walls - three in the basement and another in the upstairs family\/dining room. I think we found the speaker wires in a closet in the basement (see attached photo). There appears to be five sets of these wires (one bronze and one silver per set). The previous owners never touched this before. Does anyone have any suggestions on where to start to try to use these speakers? What type of equipment would we need? Thanks in advance!!
