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

I am assuming, based on your posts, that if I got the amp back closer/between the speakers and could reduce the length by half, that I could then use a slightly smaller gauge, perhaps a 3AWG x 2 would then suffice?.......Or did I forget something?...........I agree that attempting to solder cable that heavy without a professional level machine would be a bad idea, so crimping seems to be the way to go.........However, I still don't see how I connect them to my amp's binding posts. I could use some sort of stand-off on the speaker terminal blocks, but the binding posts on the amp are unlikely to accept that large a spade lug..............I'll have to pull my amp and make some measurements to be certain.

If I do this, I will of course pass on the results for the benefit of anyone else who may be interested.

Regarding your say: "I am sure you have noticed the difference in attitude that other posters have towards your original post and ideas after you have started explaining your thoughts and giving practical examples",

I can't explain any of that attitude as long as we are dealing with a pure technical thread. You can rather accept, decline or ask about it. What would the attitude do with it?
I thought that we are all here because we like this hobby and would be happy to do whatever it takes to get a better sound out of it.
This attitude mostly comes when some interest is involved. I don't care. Most are getting a bit excited when cables issues are brought up.
I know well why the attitude changed all the sudden. I never expected it to go well from the beginning. I needed to earn your trust as you don't know me.

Showing off with my resume would help ether.

I also had to keep my ground put, against all the "attitude stuff" to pass that storm.
I came with a will to assist and I never changed that attitude. Some just crossed the line, so I most likely won't keep answering them.

It will become really interesting when those who tried it out, will start sharing their experience.

Yes,  the terminating the 0-3x0AWG conductors will be the challenge in these DIY efforts.  

Be careful, kosst, he might show you his credentials. 🤭
