In this video I go over the hardware I selected for the project. There are a variety of ESP32 boards available on Amazon, also you can get the LM386 Power Amp and a speaker on Amazon. I also show the circuit in operation in my car.
For compatibility with the 3D printed enclosure-- the speaker I am using is 2 1/4 inches in diameter.
