I'd strongly recommend against that. The amp you are using would be delivering power not only to the speakers, but would also be trying to force it backwards into the output transistors of the other amp. That's a recipe for bad sound and likely increasing the odds of equipment damage. You might consider using a switch to totally disconnect the unused amp, but that's just another item in the circuit.
