This thing will not work for rear surround sound speakers. The connectors are RCA plugs and all A/V units I have ever seen have only speaker wire connectors for rear speakers. RCA plugs are low, constant power connections. Speaker connections are variable amplified connections. The two are NOT interchangeable. This thing may have some uses but surround sound speakers is definitely NOT one of them!
