Found a circuit:
http://openbookproject.net//electricCircuits/Exper/EXP_6.html#xtocid158349
What parts would have to change if I were to use +/- 6VDC instead of
+/- 12VDC, and use a 4 ohm speaker instead of an 8 ohm one?
Would it still work if I use +/- 3VDC?

Change the 10k on the final to 4.7k (or lower, for the +/-3V version).
The circuit is going to have considerable crossover distortion,
particularly as frequencies go up and the slew rate across 0V increases.
But it's a teaching web site, and you'll learn something.

Find a circuit DESIGNED for low supply voltages.
