If cable's electrical resistance is too high, what (in sound) would result, besides quieter?

Let's say a cable used for line-outing into an amp. Volume cannot be controlled by the source device.

If the cable's resistance is abnormally (according to your own definition) high, would there be less bass (or anything) than a low-resistance cable, provided that the amp's output volume is the same for both cables?

It would act like a resistor and reduce power.

Depending on the amp's input-impedance curve it may also alter the electrical frequency response. But that's really a hypothetical scenario. Amp inputs have impedances like 10 or 80 kΩ, whereas interconnect cables usually have <1-3 ohm, depending on the length and the conductor diameter. So even a massive, unrealistic 100 ohm cable resistance (let's say from thin carbon fibers) won't affect neither the volume level nor the sonic balance.
