50W car audio amplifier schematic circuits

Car power amplifier uses SI1050GL IC as the main amplifier. The output power 50 Watt 8 ohm mono impedance. Up to 25 Volt DC voltage. with source voltage of this amplifier car battery has to work.




Minimum of 12 Volt battery voltage, less than a sound or audio is issued less than the maximum and less good. You can assemble  this circuit amplifier with a schema like this.

Part List

R1 = 100K

R2 = 1R

C1 = 2.2uF

C2 = 22uF
C3 = 100uF

C4 = 0.1uF

C5 = 100uF
U1 = SI1050GL

If you want to make stereo amplifier , you must required multiply the two of components.
