In most cases you would want to leave it off. If you are using
multiple 8 ohm speakers then when two are connected they are probably
parallel. That would be 4 ohms. Practically any decent amp is going
to handle a 4 ohm load. Yes, you could drive it into clipping easier
with a 4 ohm load than an 8 ohm load. What's the amp and are you
expecting periods where you push some of the limitations? Above 2
speakers then the unit is probably combining them both parallel and
serial to achieve some load between 4 and 8. Often damage comes from
driving amps into clipping where you end up with larger periods of
straight dc voltage in the output. Bad for stuff. Solid state amps
are directly connected to the load so it is easier to overload an amp
with 4 ohms than it is 8. If your amp has some sort of protection
circuitry then that would be all the more reason not to use the
switch. The switch is probably adding resistance. That's pretty much
a waste as any energy used up by the resistors is not being turned
into sound.
