I have 2 different types of 4 gauge wire for powering my amplifiers approximately 60 amps of current being drawn through the wire, and was wondering what is better, a very fine multistrand wire, or a coarse multistrand wire and why one or the other?
Thanks
Matt
they say current runs on the outside of a strand of wire. (tho there is no possible way to test this theory) so finer the strand the better you are.

menace is correct.....the more fine strands you can get, the "easier" the current will flow...It will not flow "more" current.

The above posts express theories. There is no measurable difference in performance for any power cable from solid core to million-strand. There is no such thing (scientifically) as "making it easier for current to flow." As long as the insulation is sufficient for the voltage and the total cross-sectional area of the conductor is sufficient for the expected current flow, wire is wire. Finer conductors tends to make it more flexible and easier to handle.

Your correct DYohn.I'm a electronics instructor P/T and my favorite is DC and AC theory and ckt's.I love the sales people that brag about their multi stranded cable carrying better than some thicker stranded stuff.Yes it is accepted theroy that current will "skin" .But that is for alternating current.So in other words it would make a difference for your speaker cable but not your power cable.Just get the proper gauge of cable and make sure it is flexible enough for your installation.

From what I was told, skin effect doesn't even become measureable with super sensitive equipment until the very limits of our hearing at around the 20kHz point. So I don't think you need to worry about your speaker wire either. Unfortunately there is a lot of voo-doo marketing coming from wire/cable companies that spread this stuff to sell their products.

That is right, Steven. Skin effects become measureable at RF frequencies (MHz range and above.) It is not applicable to audio.

For power it does not matter. For speakers a solid core conductor is best.
