I think I kind of understand what you are saying. Something *similar* happened to me while wiring my speakers: One of my speaker wires coming out of the receiver (specifically, one of the front speakers' signal) was accidentally touching a ground, and that caused the other speakers not to work at all (the ones that were already wired up). Basically, whenever you are testing a single speaker, make sure the other 6 speaker wires are not touching any ground.
