A whine coming through speakers that increases with increasing RPMs. That
is a bad ground or a soon to be bad alternator?

Do you have an aftermarket stereo system in the car?
Usually this happens when speaker wires or RCA inputs are ran next
power wires going to the battery. As the RPM's increase you hear the
alternator "whine".
If you do have an aftermarket stereo system make sure that you run your
power wires on one side of the car, and the speaker wires or RCA inputs
on the other side or as far away as possible.

That, or what I've found to be even more common is a ground loop. This
usually happens when there is an AMP or other signal processor and it is
grounded in a different location that the radio. Usually running a good
solid ground wire from all the aftermarket gear to the battery clears up
almost all alternator whine.

bad ground/some other wiring issue.
if after you're done, it's still not perfect, look into aftermarket plug
leads that have a spiral wound core - they clear up a lot of electrical
noise.
