Speaker cable gauge and amplifier power


Based on my limited understanding of electricity, sending electricity through a wire is like sending water through a pipe. Using a larger cable gauge or bi-wiring will increase the amount of current required from the amplifier.

It seems like there must be a way to optimize speaker cable gauge and length based on an amp's current and watt ratings. Lower powered amps would mate best with narrower gauge speaker wire, and a powerful amp would benefit from thicker wire.

Am I oversimplifying, or are there established guidelines based on calculations of current, capacitance, etc.?

As Albertporter stated, from a current carrying viewpoint all speaker wire size is overkill. I must admit that I have gone along with the heavy wire idea, although I have not used any of the specialized speaker cables with exotic construction.

Recently I tested some Nordist flat cables vs zip cord, and had to admit there was a very obvious difference. My plan of action is not to purchase $6000 worth of wire, but rather to purchase fan-free monoblock amps that I can loctate just inches behind my MG1.6 speakers.
Albertporter...As Sean (the missing Sean) has told us many times, some wire with exotic construction CAN affect the power amp in undesirable ways unless terminated with a Zoebel network. I don't think that cables can do the opposite...make the amp work better.
