My A2-300 sub stopped working after about a year and half of light use. All the lights are normal as usual but it doesn't produce any sound. When I ran full auto MCACC on my pioneer VSX 1019AH it won't detect the sub, if i manually specify the sub it says the volume is too low, although it is all the way up. It is also wont detect the center speaker, but that one works as well as the other four speakers. I am using regular sub cable to connect the two. I am posting this here hoping this is something simple that I'm missing and waiting for an advice, I know I need to call ED but I don't want to wait till Monday. Please help.
