Normally this is.
Based on a fully complementary pnp npn configuration the tda7386 allows a rail to rail output voltage swing with no need of bootstrap capacitors.
This is a 4 1 amplifier schematic diagram this diagram we can use as a car amplifier or also we can use in the home this is home theater amplifier also.
This power amplifier using or based on ic tda7377 that the tda7377 ic has 4 channel input and 4 channel output.
Par speaker 50 watts.
When using one of our amplifiers big or small you always need a volume control and preferably also a tone control.
Here in this circuit diagram can make 200 watts.

The extremely reduced boundary components count allows very compact sets.
This circuit operated with 12v symmetrical dual polarity power supply.
For using 2 1 power amplifier on two channel is bridge to one output so the output is 3 channel one channel using for bass or subwoofer speaker.

And the other 2 channel is using for mid and treble speaker.
In this amplifier the audio gain is fixed 26db the pin 10 svr capacitor should not be less than 10 microfarads and helps to reject noises from the power supply.
This is the circuit diagram of stereo pre amp with volume and tone control.
