which is the best one?
Any idea of the Pros and Cons of differential line speaker audio amplifier?
what if if we short the negative line to ground and drive only positive line with single ended amplifier?

I sincerely doubt if the speaker can tell the difference between symmetric and asymmetric signal.To me,bridged amplifier is useful mainly when the PSupply voltage is not enough.

Before you connect, check the dc voltage level. dc signals are unwelcome by the speakers since it causes static power dissipation in the speaker coil itself. Differential line speaker audio amplifier is sensitive in the dc offset between the differentail output terminals.
