The Sketch is correct!
20A on 120AC is way different than 20A on 12DC.
A 100 watt light bulb will draw about 0.8 amps on 120AC.
Where as a 100 watt amp will draw about 8 amps on 12DC.
Amps = Watts/Voltage
Copper is copper, so 12AWG domestic wire will have "roughly" the same current caring capability as 12AWG speaker wire...
And as HisSketchiness said the domestic wire will be a lot more rigid than and stranded speaker wire.
