Build from scratch, speakers, resistor and capacitors from old analogue TV.

Mosfet Tip31c: bit.ly/tdjgdsa
Step down module: bit.ly/2Wffql4
Power jack: bit.ly/3a5hGTx

-Input 6V, use heat dissipator.
-1k resistor ,16V 100uf capacitor.
-Schematic at 2:15

-Sound is clear in highs and mediums, the bass is not very strong.
-Using step down converter to supply 3 Volts to the blue led.
-Simple to build, easy design, i´m happy with the final result.
-12 volts is the max power supply, 6V to 8V is recommended.
-Heat dissipator from PC motherboard.
-Tested also with 0514 transistor.
