Hi Zombie,
The peak current in the amplifiers is doubled with a 4 ohm load (compared to an 8 ohm load) and the current is doubled again when two amps are bridged. So the protection circuit in the LM3886 will drastically limit the power when bridged into a 4 ohm load.

You said "It doesn't work well on 4 ohm speakers" so it appeared that you didn't know why.
Some people connect so many speakers in parallel to the output of an amplifier that it is driving nearly a dead short.

What didn't you get? with 8 ohm speaker it works just as expected.
