No one actually knows how to lculate what speaker cable they need


It goes back to cable manufaturars, mostly provide no relevant data! to sales and the users. None will answer this!
Whay do you think that you own now the optimal cable to your setup?
I think I've figured it out.

I never lost one until this thread.
Same here @mitch2 .
Absolutely ridiculous claims in this thread. Like someone pointed out - OP is trying to market his ideas here, the same he did on another forum. Wonder when he is going to open up his business.

Ya, some business. If the OP doesn't approve of your amp/speaker combination he will refuse to help you. It's like a revisit of the Seinfeld soup nazi episode: "No Cables For You!"

b4icu,
Hi Michael,
just to update you, 4AWG cables expect 7 Nov from Amazon. Spades and banana connectors stuck a warehouse in Oregon awaiting reset of password which I forgot.
sorry for the delay
