32W Subwoofer Amplifier

1- Operational amplifier TDA2050 which is used in the main amplifier circuit 2- TDA1524 which is used in the pre-amplifier of the circuit. 3- I used the split DC power ±22V as an external supply. The main advantage of the split supply over the single supply is that it is filtered from both sides (+) and (-) terminals and has the proper grounding system which are caused to decrease the output noise of amplifier but u can use single supply too.
