Oh go do it. I don't think that the second set of cables left attached to the amp changes any of the parameters of the amp at all. Think about it......
But, shorting is a REAL issue! What I have done when necessary is to tape the wires with spades so that the + and - wires are well away from each other and can't under any circumstances touch. Ditto for banana plugs if they are individual plugs (not two encased in plastic, seperated the proper space to match to many speaker and amp connectors).
Re the taping, hell I'm so anal about the shorting potential I tape all of my loose ends, spades, bananas, whatever, so they can't short if one or both were to come loose from the speakers or amps. Highly recommended!
FWIW.
