Can I connect 2 speakers to the same output of the LM386 audio amplifier?

The datasheet shows that an LM386 works well driving an 8 ohm speaker to 0.5W when powered from 9V. With a 12V supply or when a 4 ohm speaker or two 8 ohm speakers are in parallel then the total output power is almost the same but the IC heats up much more. If you connect two 4 ohm speakers in series then their total power will be the same as with one 8 ohm speaker.
