Hi. I am running 40' 14 gauge wire from my receiver to my rears. The speakers are 6ohm, my fronts and center are 8 ohm speakers and the receiver is 8 ohm as well. Last night the dog ate one of the cables going to a rear and I reconnected the wire using some tape. (It was my fault though, I left the cable on the carpet behind the couch and she likes to go under there very much...) There's no problem soundwise, I checked the SPL and it's fine. But I am wondering if this connection drops the impedance of the cable and put extra load on to the receiver?
