No one actually knows how to lculate what speaker cable they need

Mr. batenet

Sorry for the "A". I'm still waiting to be answered about the DF of your amp. Most likely it will arrive after the weekend.

Could you please elaborate regarding your amplification configuration? That might have some significance on the recommended cables. 

10 mono blocks…?

Thanks.

I just want to listen to my music. I like what Steve said. And I dont want to spend a ton of cash on cables. I do understand powering my equipment.  Mainly the amp. I have 4 double gang boxes on the back wall, each is a 20 amp circuit. So my amp is dedicated to a single circuit. I will eventually use a 12 awg cord to get the full power from the circuit.  I do understand one thing about electric,  the long you run the thicker the awg. 12/2 is in the wall and going any larger will not get me anymore power. Actually it would be dangerous to go a higher awg off the wall, don't want to heat up the lines in the wall. 20 amp from the breaker is all u will ever get and 12/2 is the feed. 12/2 does have distance limits. Unless u have 10/2 or 8/2 in your walls which no homes have except for dryers, ovens. Or you ran your own wiring. I know we are talking about speaker wire. But I thought I would throw in my electrical experience.  My 2 cents.

Mr. ppc67
This thread is about speaker cables. I would prefer not to open her a discusion on electrical wiring in the walls. Please fell free to open your own thread. Thanks.

b4icu,

You misunderstood my (fully hypothetical) question and cut it in pieces that lost the original meaning in the process.

"How thin is that last connecting piece on the 0 AWG wire allowed to be" I'd answered that already before! It should be as thick as possible, or as thick as the banana plug can get.

The question was, in fact,...

How thin is that last connecting piece on the 0 AWG wire allowed to be before it can be considered a fuse?

Not that I expect anyone to have an answer, or speaker cable to become a fuse, but there is a conceptual similarity in things I mentioned (fuses and thin wire attached to the thick wire).

"If you think of an 8-10 gauge wire as a fuse, you are wrong! The 0 AWG is the fuse in that system…"

You got me on this one. I could have sworn that every fuse I have ever encountered had a filament inside that was thinner than the wires it was placed between. I stand corrected although puzzled by this development in electrical engineering. I will blame the dogma they taught me in elementary school and my lack of keeping up with reality. I am too scared to find out why thicker wire would, in a fuse, burn sooner than the thin one. In my, admittedly mislead, mind I thought the thicker one conducts better and, sort of, more. Not to make it a wall wire thread, although it deserves comparison, but I cannot but think that we should have been putting thinner and thinner wires in the wall if we wanted carefree conduction.

Which might have been the point of all those manufacturers selling hair-thin speaker cables.

Whatever it is, I am puzzled.
