This may be the dumbest post ever placed here but... I've hooked up a zillion stereo systems over the years, usually is a simple task but the new fangled methods of connecting the speaker wire to the receiver has me quite frustrated. Maybe I just dont "get it". My Panasonic SA HE-100 has type of speaker terminals for the surround sound and center speakers that results in either keeps coming loose, or it shorts out, I'm not really sure what I am doing wrong. After a couple of days with the receiver I lost sound to the rear speakers and could not for the life of me figure out what was wrong. Eventually I discovered the speaker wires were not making a good connection at the receiver's terminals. The receiver has speaker connections for the fronts that are straightforward and not a problem, but the surround/rears require one to insert the wire into a hole and then push the red or black tab UP (for red) and DOWN for black. Not the spring loaded, push tab terminals that I am used to. My 14 gauge wire seemed too big for these terminals, but even after trimmming the width I had difficulting make a connection that would withstand movement of receiver or slight touches of the wire associated with me installing other connectors nearby. I tried 18 gauge wire and had a similar problem with it, it would fit nicely into the little hole but it too would come loose with slight touches or movement. So now my connections but any touch to the wire will cause it to come loose of short out. Am I missing somthing really obvious about this type of connector? I do not understand the way they are supposed to work. The old fashioned push-tab ones were easy, maybe there is a trick to working with these nasty push up/pull down types? Believe it or not , I have spent two hours trying to solve this problem without success.
