This is essentially "shotgunning", although to be truly "shotgun" you need to run one cable to each leg, such that the pos and neg of each cable are tied together, and then each cable bundle is run pos and neg.
This is not my understanding of "shotgun".....
"Shotgun" means that for each speaker there are two identical runs of a single cable. Each cable has a + and - leg at each end. That is, two + legs and two - legs for each speaker.
The ends can be handled in different ways:
AMP ENDS: (a) + and - can be left separate, meaning there are two + and two -
or, (b) the two + legs are combined, the two - legs are combined, such that there in one + and one -.
SPEAKER ENDS: same as above.
If speakers are single wire, (b) would apply.
If speakers are biwire, (a) applies and one cable connects to the HF speaker posts,
and 2nd cable connects to LF speaker posts. (This is superior way to connect biwire speakers as each post pair gets a full cable. Typical bi-wire cable is simply a single cable, split into 4 legs at the speaker end.)
If amp / speaker only has single pair of posts, ends can still be left separate, but must be terminated in such a way that both + (and -) ends can get onto a single post (ie: spade / banana; or spade / bare; or banana / bare, or bare / bare)
This is what I always thought.
Over the years, I've come across
much confusion on this issue. It's completely possible I'm confused too!
