Here is a modification of above speaker cables: Twist the red and black wires together, one pair at a time. Then, put all of them in one large bundle and slide into some nylon flex housing in a color that complements your system. Use the red for the hot and the black for the ground. Do the same of the other speaker.
This will lower the inductance a lot in comparison to the above method, which is the big problem at these currents and impedances.
I forgot to mention this above, you can make this cable where each wire is as large as 12 or 14 gauge but it starts to work against you at wire gauges larger than that. This is because the inductance starts to increase with larger diameter wires; you simply can't get them together close enough to reduce the inductance. This is not to be confused with "larger wire has less inductance than smaller wire". Although this is certainly true, I am speaking of mutual coupling to reduce the inductance. Hence, eight 18 gauge pairs will have less inductance than say four 12 gauge pairs.
If someone opts to build this, drop me a note with your experiences.
