Amplifier Driving 8 ohm speaker | All About Circuits
https://forum.allaboutcircuits.com/threads/amplifier-driving-8-ohm-speaker.90372/
Oct 14, 2013. #1. There is audio signal which I want to amplify because when the audio is on, the signal is about 2V p-p, but when it is connected to the load, the signal drops to 400mV. This makes the volume too low. I used the lm386 ic, and here is the schematic. The sound is loud now, and sounds fine when the audio is playing, however, when ...

Connect the 8-ohm, one-watt speaker to output pin 5 of IC1 through C3. Switch on S1 and keep VR1 to its mid position. Now, take a screwdriver and gently touch it on input terminal pin 3 of IC1. You should hear a humming sound from the speaker. This will confirm that your circuit is working and ready to use. Note.

You can check the datasheet, the output power depends on your power supply voltage and the impedance of your speakers. For my amp, I had 8 ohm speakers with a 9V power supply (using the LM386N-1) and my output power is 500-700 mW. This amp is too small for 440 W speakers, for those you’ll want to look at the LM3886.

The Simplest Audio Amplifier Circuit Diagram
https://www.build-electronic-circuits.com/amplifier-circuit-diagram/
The amplifier circuit diagram shows a 2.5W * 2 stereo amplifier. You can also make a 5W mono amplifier out of it. (Check out the TEA2025 datasheet for more information on that) On the input side, you should use a dual potentiometer. A dual potmeter allows you to connect both the left and right channels on one potentiometer.
