I briefly explain electronic components needed to build a bluetooth speaker/streamer.

Parts used:
Raspberry Pi zero w: you might want something more powerful, you can always find use for more processing power. Don't be cheap with power supply, it can produce noise.

Audioinjector Octo soundcard. In general the combo has good sound quality, but feels a little raw. Pops on power off, produces weird noises on startup, and also picked up noise when used as a hat (without wire)

2 ice50asx2 amps: one for each satellite
ice125asx2 amp for subwoofers: planned to have 2 subs initially. Would use ice50btl instead

Good rpi setup instruction:
