I think what you are asking to do would be Bi-AMPING not wiring. Bi-wiring will, like Mike C said, not give you any audible difference. Bi-amping, on the other hand can make a difference but more than likely only at VERY high volume level. You will not see 65W doubled going into your speakers, either. You will more likely see something closer to about 50wpc, or about 100 watts total to each speaker, and that is as a max, again at very high volume levels. Hope this helps a bit.
