How To Make It.............??
Circuit Diagram
*Watch the circuit diagram and follow my steps for make this circuit.
*First you need 7388 ic. This ic is 4 channel class AB amplifier. It give you 45 watt (maximum) output per channel.
*1 no pin.........Connect GND.
*2 no pin.........Connect GND.
*8 no pin.........Connect GND.
*13 no pin.........Connect GND.
*18 no pin.........Connect GND.
*24 no pin.........Connect GND.
*11 no pin.........Connect 104j capacitor and and input here (Input 1).
*12 no pin.........Connect 104j capacitor and and input here (Input 2).
*14 no pin.........Connect 104j capacitor and and input here (Input 4).
*15 no pin.........Connect 104j capacitor and and input here (Input 3).
*3 no pin.........(output 2) Connect speaker[-].
*5 no pin.........(output 2) Connect speaker[+].
*7 no pin.........(output 1) Connect speaker[-].
*9 no pin.........(output 1) Connect speaker[+].
*17 no pin.........(output 3) Connect speaker[+].
*19 no pin.........(output 3) Connect speaker[-].
*21 no pin.........(output 4) Connect speaker[+].
*23 no pin.........(output 4) Connect speaker[-].
*4 no pin...........Connect 1uf capacitor [+] and 10k resistor (1/4). Then connect 1uf capacitor [-] with GND, and connect the 10k resistor with 3-5 volt for ST-BY.
*22 no pin...........Connect 1uf capacitor [+] and 47k resistor (1/4). Then connect 1uf capacitor [-] with GND, and connect the 47k resistor with 3-5 volt for MUTE.
*10 no pin.........Connect 47uf capacitor [+] and [-] connect to GND.
*16 no pin.........Connect 0.47uf capacitor [+] and [-] connect to GND.
*6 no pin.........Short with 20 no pin.
*20 no pin.........Connect 4700uf capacitor's [+] with 20 no pin and connect capacitor's [-] connect to GND [Vcc].
*For Vcc you need 12 volt 15 amp power supply.
