OK Im not sure which connections to use for my speakers. I got a new receiver but not more speakers. Should I use the surround Left & right connections or the surround back? The rear speakers are mounted on the rear wall which is where the couch is located so they are above our heads to the left and right. Will I lose effects using one set over the other? The manual really doesn't explain which connections to use if you only have 5.1 speakers with a 7.1 amp.
