Hi, I'm pretty new to the 'good' speaker game so here it goes. I'm trying to set up my surround sound, I'm following the user guide that came with the amp and when i run the auto setup it wont detect one of my rear speakers. and my front right speaker. Instead when it plays a test for the left and right speaker both come out of the same speaker. I also tried setting it up manually and that wont work either. Not sure what I'm doing wrong. I have two polk rti a7 front speakers with the polk 12" sub and just two cheapy missil speakers i got for $20 (they both work perfect) Any help would be great !
