I think you're off by a decimal point or something on that cable
resistance estimate. My table shows gauge 0000 (quad-aught) copper
to be .049 ohms per 1000 feet  (.16 milliohms/meter, let's think about
moving this archaic country into the metric system!)
No. 6 copper is shown as .395 ohms/1000 ft  (1.3 mohms/m).
These numbers are for solid wire, but I believe stranded wires are
gauged such that a stranded wire has roughly the same resistance
(same order of magnitude, anyway) as solid wire if the gauges are the same.
Is this true?

Sorry this doesn't have much to do with audio, the previous comment
about wire heating vs. total resistance is the important point. Both
power and voltage drop should be kept low enough. For more than a meter
or so, the voltage drop constraint wins, for short distances the power
drop (wire heating) constraint wins.
