RE: 2 amps - 1 pair of speakers

One amp will "see" the output impedance of the other amp in parallel with the speaker impedance. Granted that you say one amp will always be "off" while the other is "on", I guess the output impedance of an M60 when it is powered down would be infinite, and therefore it would be OK vis the other amplifier. But do check whether there is a finite R across the outputs of the other amp when IT is powered down, before you go ahead with this, and DO check to make sure I am not wrong about the M60. (Just put your ohmmeter across its outputs when there is no AC applied.) And DO install some safety mechanism, so you won't forget not to power up both amps at the same time. At the other end, check also what's going on.
