  • Depends on which setup you’d like to go for.

    Disassembly aside (no idea how Alexa looks like on the inside), you could go for something simplest: take a RPi 1B/2/3/4, plug in the 3.5mm jack into it and solder the other side directly to the speaker. This, in theory, should work out of the box and give you some decent sound (and probably even okayish volume).

    If you want to go more elaborate, you might use some smaller/cheaper computer (e.g. RPi Zero 2W) + some tiny external DAC+amplifier. In this case you will have to ensure that the DAC is compatible with your computer, that the software is there and also handle power supply to both of them, and possibly also take care of the 50/60 Hz hum induced by it (depends on the power supply, the DAC and its wiring).
