No kidding there would, if the 22ga wire was longer than a foot or so.
Its comparatively high resistance forms a voltage divider with the
speaker's load impedance. Since the latter is usually far from flat,
you get a built-in EQ curve following the shape of the speaker's
impedance. Not desirable.
Thanks, Paul!
This makes a great point about oversimplification of these circuits, and only
looking at essentially one factor (current capacity).
Fine for powering tiny hobby motors and small light bulbs (assuming their draw was
low enough for that slim wire to handle), but with audio the overall effects of wire
as a circuit element cannot be ignored.
