Your choice of speaker wire gauge and the length of the runs also
affects the speaker impedance load presented to the amplifiers. As
you can see in this table, even fairly short speaker runs can have a
very significant resistance if you use a smaller wire gauge. This can
be a benefit if you paralleling lots of speakers. The wire itself acts as
an impedance limiter, since the amplifier cannot see a speaker load
lower than the resistance of the wire. The downside of this resistance
in the wire is that you waste the total power available to the speak-
ers. All that resistance in the speaker wire will turn some of your amp
power into heat.
