The Heart of This project is TDA2040 IC it is an Audio Class A&B Amplifier the maximum output it can provide is = 22w it can provide Low harmonics and high current at out put it has ability to Protect the ic from short circuit.
Good news is that you can operate this circuit using your car battery (12v Dc battery) Connect a speaker with 8 Ohm impedance to produce good sound.
Must Attach Heat Sink with TDA2040 ic otherwise it will burnout because it can produce too much heat during amplification the rest of the circuit is very easy R4 is used for feed back and We all knows that we can use capacitor for filter.
