@pinwa...I twist all (4) conductors together for a single stick that runs JUST the positive OR JUST the negative of ONE speaker only. So you need (4) sticks total. I've tried it just putting another normal run on top of each other, but this way is totally better sounding. It produces around a ~8 gauge wire.
I was in the high-end audio business most of my life, so yes, I've owned/sold/listened to many, many, many brands.
@jetter...I not really sure why it's supposed to sound better? It so inexpensive that it's easy to try. We shall see.
