Speaker Cables

[daniel.avasilichioaei]

I'm not an expert, but, as far as I understand, we are talking about a circuit in which they are put in series:
- a power generator (amplifier)
- a resistor (speaker)
- the two connecting cables.
The speaker has a resistance (more precisely impedance) from about 4 Ohms and up.
What is the relevance of the resistance of the amplifier and of the cables, in the conditions in which it is of the order of 0.01 Ohm? The speaker has a resistance hundreds / thousands of times higher than that of the cables...
