to get more available current? I'm going to say the best advise will come from the owner's manual. You don't want to mess up this new receiver. I would say that, unless the two sets of posts come from separate driver circuits, you get no potential power gain.
I am getting a pioneer vsx 1019ah-k reciever. I have a C3 klipsch center and def. tech. 7006 fronts. That is all I have hooked up. My center has two sets of pos and neg connecters. Can I Double the power by connecting 2 sets of wires to my center and reciever to get more power to it?
