The distance between the amp and the mains matters the connection between the amps speaker terminals and the subwoofers amp's speaker terminal s does not as you are just connecting the two amps together to feed a signal forward. I have never daisy chained a subwoofer off of the main speakers terminals as the recommendation from the subwoofer companies is to use the amps terminals.
Gotcha......
But aren't the two connection methods effectively the same thing? I mean, it's basically main amp connected to sub amp, with some binding posts thrown into the mix when jumping from speaker posts. If so, and assuming no sonic detriment to jumping, why would one be favored over the other?
This is what I'm trying to get a handle on.
