John,
Without going into a long technical discussion, it is safer for your
amp to set it to the (numerically) lower impedance, which is the 4 ohm
setting, assuming your choices are 4 or 8 ohms. You may loose a bit of
output power, but it certainly won't hurt anything. However, you may be
asking too much of the amp, especially if you want loud volumes with all
of the speakers switched on at once.
