How to make stereo amplifier

How to make stereo amplifier :

This is a 2.0 amplifier circuit diagram. this is a bridge mode circuit. this circuit is based on STA540. this IC has 4 inputs and 4 outputs. but here it’s made in bridge mode. now it’s a stereo circuit. Right and Left speakers. this is a 17+17=34 watts amplifier. this circuit can run from 8 voltage to 22 voltage. 

How to make 2.0 amplifier

We can use 8-voltage to 22-voltage. watts will depend on the voltage. 

we can connect directly with the speaker.
