The factory delco radios require 10 ohm speakers. Is it possible to use 8 or 4 ohm speakers without causing damage to the radio?

Four will rapidly burn out the output transistor in the radio (too little impedance = too much current = too much heat).

Circuit is designed for 10 ohms. 6 is too low. You can tie (2) 4 ohm speakers together and make 8 ohms. That would be closer.
