Power Amplifier Circuit 2 x 20 W stereo with IC AN7156N
This circuit operate with IC AN7156N . You just can use this IC , because havnt similarity it. In this Circuit have 2 input IN R and IN L and have Output R and L . Voltage supply require 15 V , minimum voltage 9 V and maximum voltage 24V . And the voltage must DC voltage , and better the DC voltage filtering .
Maximum Output for 1 speaker 25 W , so this circuit have maximum output 2 X 25 W with minimum impedance 4 ohm. See this circuit schematic below :

600W subwoofer audio amplifier with 20 channel mixer and parametric
This picture below is about my setup subwoofer amplifier with 20 CH mixer and parametric. This amplifier use transformer 10 ampere to supply the power and 3 ampere transformer use to supply mixer and parametric.Elco capacitor that i use for the transformer 10 A, only 10000uF numbered 2. The circuit of amplifiers that i use which is 600 watt mono subwoofer amplifier . And booster amplifier only use 2 Sanken transistors. See picture subwoofer amplifier assemblies below :

9 20 Volt amplifier circuit
For this time I will post the scheme following an amplifier of the IC KA2203, SN16975, TBA820, UL1482P. Which has 4 Watt power output with 4 Ohm impedance. At least 8 Volt supply voltage and a maximum of 20 volts.Part List
R1 = 100K
R2 = 56R
R3 = 56R
Use 1/2 W resistor
C1 = 47uF
C2 = 100uFC3 = 100uF
C4 = 470uF
C5 = 470pF
C6 = 0.22uF
C7 = 100uF
U1 = KA2203 , SN16975, TBA820, UL1482P
