Speaker Protection circuit diagram:
This is the speaker protection circuit diagram. All amplifiers should have this circuit. This circuit disconnects the speaker if there is a problem with the amplifier. If an IC or transistor shorts, voltage will appear from the audio output. This circuit is necessary to protect the speaker. If voltage is applied to the speaker, it will burn the speaker. This circuit works with a 12-0-12 voltage.
every amplifier needs this circuit
