Power amplifier circuit with IC LM386

IC LM386 is working for the amplifier audio circuit with a low power output , range from 0.325 watts to 2 watts with impedance 8 ohm. In this circuit requires voltage of 12 volts to the maximum work, and maximum current 3 Amp.
Components List :
R1=33K / 0,25W
R2=1K / 0,25W
R3=10R / 1W

C1=100n
C2=0,1uF/35V
C3=100uF/16V
C4=220uF/35V
C5=4,7uF/16V
IC1=LM386

Connector Instruction:
X-1  = Input , connect to output
X-2  = Input Ground
X1-1= V+ , 12 Volt DC
X1-2= V-/ Ground
X1-3= Speaker+
X1-4= Speaker-
