Sounds like the audio amp is too powerful for the speakers if it permanently damages it.

I'm betting the amp is integrated into a multi function chip or codec where it was selected because of integrated features rather then matched to the required speaker power.

A speaker which can handle 2 watts RMS on music material might very well blow up if fed 2 watts of square wave. The coil overheats since it's not moving. This is why clipping not only sounds bad, but is dangerous for drivers. https://en.m.wikipedia.org/wiki/Clipping_(audio)
