I have an Onkyo TX-SR508 with some BIC Acoustech PL-89 Speakers for Front. The problem is that they were cleaning my room and move my speakers and they connected the two wires to one port i.e. Red & Black. I quickly put it back when I noticed it wasn't working, but now I have a problem. That speaker doesn't work completely when its at low level, but for some reason when I high the volume to a high level, it triggers it to turn on. Can this be the Receiver or Speaker that is screwed up. Thanks!
