Building an Audio Amplifier : 4 Steps - Instructables
https://www.instructables.com/Building-an-Audio-Amplifier/
Building an Audio Amplifier. A general purpose audio amplifier is very handy in many projects that are related to audio. This project, which can be completed within a few hours, is a more advanced version of the simple LM386 based amplifiers projects normally found as provides a safe connection to external devices (e.g., smartphones, PCs etc.) and provides a x200 gain …

The LM386 is quite a versatile chip. Only a couple resistors and capacitors are needed to make a working audio amplifier. The chip has options for gain control and bass boost, and it can also be turned into an oscillator capable of outputting sine waves or square waves.

Just connect the PNP base thats connected to the source to ground, amplify about 10 to 50x then check the voltage on the output. If the voltage is too high or low (relative to ground) turn the trim pot till she outputs 0v. (The trim pot is adjusting the DC offset of the amplifier while the normal pot is for amplifying) Why two 8 ohm speakers?
The Simplest Audio Amplifier Circuit Diagram
https://www.build-electronic-circuits.com/amplifier-circuit-diagram/
Connect the circuit diagram as in the one marked with “Amplifier with Gain = 20” and you get 20-fold the signal. If you need exactly 6, you can play a round with the resistance on the input. For splitting the signal, you can use resistors for basic splitting. Google “signal splitter circuit” to see some examples.
