Need help with amplifier

Audioguru again:
I agree that the datasheet does not show BTL driving a 4 ohms speaker because with the much higher power then the IC will melt.
It can drive a 4 ohm speaker is the supply voltage is reduced enough (try 14V) for the maximum low distortion output to be a little less than 25W.

I have not thought about that, thanks for clarifying!
