What speaker gauge for my setup?

[pixelthis]

So, if your using the same guage wire but the lengths are different how do you match the resistance of the cables??????

ALL YOU HAVE to do is pay attention to the guage.
IN EXTREME cases (one foot on one side, twenty on the other)
you can have a resistance difference, but it wont matter much if you
use the same guage.
But if the short one is 12g and the long one is 16 or 20, you could get a difference.
THE RESISTANCE difference between one ft and twenty ft
wires of the same guage are slight, so use the same guage
for every channel, excepting channels with outboard amps.
WHAT guage you use on those will only matter in relation to other cables connected to the same amp.
