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

Big entertainment here,sorry for gramma and spelling!!But i´m very openminded,so going to to try bigger gauge cables just for fun,have order 0 gauge cable 8 feet pure ofc each channel  copper to my speakers,have active crossover so start with mid and top to my brigded amplifiers,and wait with bass to here if some improvments.Have Artistry Dvorak speakers and have unknown Interrim 500m amplifiers so DF?

The 500 model is very special,outperform my klass a amplifiers more than ten times the price.

Why do you think mr Geoffkait i´m the ideal candidate because only of spelling and grammar?Have been in this hobby for more than 35 years,have done construction audi components,tested many things and listened to many differnt configurations.

Mr b4icu
Abtenet (batenet) is not from Germany,but not so far away, Scandinavium Sweden.My reason for not having my amplifiers 
more close to speakers is just cosmetic.The speaker placement is about 7 foot from backwall of my room,and with all electronic equipment more than 10 monoblocks and everything else i had to organize it a bit.
 

Mr, b4icu

Thank you for your effort you put down in research of Damping factor.
Have a simple explanation about so many amplifiers,my set up is a combination of hometheater and 2-channel for music,11 channels + 2 subwoofers with amplifiers including buttkickers with own amplification,2 channel with 2 bridged Inter-M 500 to upper registers and one 500 amplifier for left and right woofers with active crossover.Believe me this korean amplifier is a fantastic amplifier for very small money,but only the 500 model sounds good.So my expensive and powerhungry class-a amplifiers have to do service in surround channels,and for serious listening in two channel my Korea design "made in Kina" .
