4 1 amplifier schematic diagram, TDA7388

4.1 amplifier schematic diagram:

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. here in this circuit diagram can make 200 watts. par speaker 50 watts. 50+50+50+50=200 watts. TDA7388 Ic number. normally this is used in the car audio player. in this circuit diagram, we can use 4 input and 4 output.

Let’s go to watch the video that how to make this circuit diagram?

We know that voltage X ampere = Watts. so 12 voltage / 200 watts=16.6 ampere.


you have to use 12 voltage 16ampere transformer to get 200 Watts from this IC.

normally this IC used on car audio sound system. we know the car battery is minimum 35 amperes 

Now you can ask How to connect 4 input. We see the computer has 3 sockets for the audio system

normally we use 2. one for Speaker output the middle one the Green one. and the pink one for

the microphone. but a blue one for What? this blue one also for the audio output device.
