Is it possible have 4 speakers playing at the same time with my stereo reciever? MY reciever only supports playing a or b speaker pair, not both. I heard that you can twist the speaker wires and put them on the same channel on the reciever. Is this possible? Dangereous for the Speakers or Reciever? does it mess up sound? I have a technic sa ex140 (can't post link but manual on amazon). Its 100 watts per channel too. I may just upgrade to surround reciever through time, but can I do this now?
