    Best Way to Wire Speakers Up

    So I am building a prop for a costume that plays music and was planning on using a Teensy with the Audio Adapter Board. Now it is all going to be contained in a small housing so I can't have large speakers, so I was thinking to use two of these https://www.adafruit.com/product/1890 or one of these https://www.adafruit.com/product/1669 What would I need to connect either of those speakers to the audio adapter board since I read that I might need an amplifier board too. Also trying not to accidentally blow out the speakers.

    Also, on the audio adapter board, is there a way to add a knob to control volume?

    The prop shield includes a dedicated Class D amp to drive a mono speaker, otherwise you look at something like https://www.adafruit.com/product/3006 or the stero versions. Key thing is using a class D amp, and not exceed your available power or space.

    For the volume control there is a default position on the audio board for one, but you need to add code to adjust the playback volume yourself. It is not controlling hardware directly.
