How many electrons?

One hundred million billion trillion zillion.....or maybe just seven.

Trick question. Between none, and a few hundred, as the electrons dont really move much in AC current, it is the wave that moves.
This is a crude and non-scientific wording, so the words may be incorrect, but the IDEA is correct.

The drift velocity of electrons in audio cables is about 1 cm/hr. So the real answer is approximately zero.

Geoff and Elizabeth, note that the question referred to "the number of electrons that move between the amp output poles and the speaker cables every second, in either direction."

As I interpret it, that clearly refers to the number of electrons moving past a single, specific, fixed location (in either direction) in a given amount of time. That location being either of the two connection points between amplifier and speaker cable (although any other point in the run could be chosen without affecting the answer). Based on that interpretation, my answer is correct.

If the question had been how many electrons travel from one amplifier terminal through the cabling and speaker to the other amplifier terminal, then yes the answer would be approximately zero. But that was not the question, as I read it.

Zero - that is obvious one
