Introduction: Loud Lm386 Amplifier

a loud amplifier

Step 1: Parts

1x LM386 amplifier chip
1x 100nf capacitator
1x 100µf capacitator
1x Speaker

Step 2: Assembling

insert the LM386 chip into the prototipyng board and solder a wire to pin 6 of the ic and connect it to positiv 9Volts then add a 100µf Capacitator to pin 5 (+ to pin 5) and connect a speaker to the - terminal of the capacitator and connect the speaker to GND.

Next, connect pin 4 with a wire to ground

then connect the 100nf capacitator to music input (connect channels Right+Left together and ground from the audio to ground)

sorry with the 5V it means 9V

yes you can use anoter potenriometer to

sorry with the 5V it means 9V

on the circuit diagram, where do those 5V come from?
And isn't 10kOhm a bit too much? I've tried that and the resistor really lowers the overall sound, because of the low voltages.
