Anyone here calculate how much power is lost/voltage drop through the speaker cables? So to size them appropriately?
For my work in real life, i often need to size power cables and calculate voltage drop and short circuit capacity for electrical installation (so to comply to code of practice).
But i am not sure what should be taken into account if i were to calculate for speaker and amplifier.
Im thinking whether the drop in voltage due to small cable size between amp and speaker will have an impact or not.
In the past, i estimate the power sent to my speaker by measuring the voltage at the speaker terminal, then square the value and divide by the nominal resistance. Then i set the limiter on my processor to limit power. But the impedance of speaker coil varies with frequency.
Maybe when im free i think about this.
Just some thinking.

Isn't that what the guy did in the video you shared? So you want to recreate this testing platform? That would be interesting.
