I'm sure that wire holds a few pF of charge. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
Anyway, I would have to do up the math which I'm not going to do because I don't care, but you might run into higher induction between the two cables. Just because of the SHEER amount of copper you have there. If that was to occur you are actually going to put a delay on the rate which the current flow reacts to demand. Also I saw several cables which were different lengths. That is a no no. They could develop under load oscillations in the cables creating harmonics and heat. Which could cause a major system melt down. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
I understand the OP's thinking process behind wanting to do this. But, there is a point where certain things are irrelevant. What is even the maximum current draw of those amplifiers? 300 Amps? Even if the maximum peak current was 1000 Amps the load of each cables (assuming 46 means ground & positive so there is 23 ground and output power cables) is 43.47 amps.
Just some thoughts.
