Can anyone explain how a tda2030 bridge amplifier works.the circuit is in its datasheet. Works on 12v dual supply. Produce 35watts RMS. I'm a beginner. Please.

The negative input of the second amplifier is fed through R7 and C5 from the output of the first amplifier.

Bcos I can't see a direct connection. When I look at them, positive and negative input of second amplifier is connected to neutral. One with a 22k resistor. I'm not a professional. So not good with circuits.

Why are you asking about resistor values that are all shown on the datasheet for the TDA2030 and the TDA2030A??

So the output of top amplifier is send to the input of second amplifier. Which value of resistor is needed to connect them?

The output of the top amplifier feeds the negative input of the bottom amplifier so their output voltage swings are doubled. With a +/-12V power supply The top amplifier output swings to a peak of +9V when the output of the bottom amplifier swings to a peak of -9V. Then the 8 ohm speaker gets 20W RMS just before clipping. When the supply is +/-16V and the distortion is very high then the output is 34W.
