connect 2 different wire gauge to pos and neg speaker terminal

The only fuse I have on hand is a 4 amp slow blow fuse. I have an older model Fluke 87 True RMS multimeter and I checked for resistance across the fuse link end caps.
With the meter set on ohms auto first touching the two probes together the meter reads 000.01 ohm.

That should read,
meter reads 000.1 ohm.

Jea48,  It is all very confusing.  AFAIK electric current (as motion of electric charge) in wire moves very fast - close to speed of light.   Individual electrons also travel fast at about 1% of the light speed (2000km/s) but they move in different directions.  What moves really slow is average speed of all electrons (drift velocity).  Back to our analogy with balls stacked in the tube - last ball will start moving the same moment as first ball (they push each other).  That's electric charge moving (electric current) at the speed of light.

The "electron drift" IS the electron velocity. Drift velocity is on the order of cm per hour. In other words they, the electrons, are virtually stationary. The "drift velocity" is not (rpt not) the net velocity due to back and forth motion of the electrons. Whatever moves at lightspeed or near lightspeed are photons. You know, the only particles that can - and must - travel at lightspeed or near lightspeed. If you want to say current is an EM wave and therefore comprises photons I have no problem with that. Thus electrons are charge carriers, they are not the charge per se.

No, actually that analogy intimates that current travels instantaneously, which cannot (rpt cannot) be true. I mean unless you’re invoking action at a distance. Current moves at *near lightspeed* which means current must be photons, no? The electrons are only charge carriers, they're not (rpt not) the charge per se.

No, it is not.  Electron drift is AVERAGE speed of all electrons.  Individual electrons move fast at about 1% of speed of light even without electric field (Fermi Velocity).

Line of balls is simplification of lattice of electrons that is disturbed at one end. As I mention before connection between electrons is not a physical one.  Electrons poses electrical charge and repel each other.  It takes time for disturbance of the lattice to travel thru wire.

Thus electrons are charge carriers, they are not the charge per se.

Electrons poses the charge - it is called Elementary Charge.  There are two forces between electrons - gravitational and Coulomb (electrostatic) force.  Gravitational is attractive but is very, very small in comparison to Coulomb repulsive force, that exist exactly because electrons have charge.
