I want to realise this project:
I have two bathrooms with a single mono passive speaker and want to use a raspberry pi do be able to:
1. use raspberry as an AMP cause the speakers are passive
2. make a mono signal out of a stereo signal
3. attach both speakers to one raspberry
4. make it possible to stream different sources to each speaker
If I can use WIFI, BT, Airplay or whatever in addition that would be fantastic.
In the end the two speaker will be part of my iobroker home automation system and I would be able t stream radio or spotify when I take a shower.
I think I can do all this with a raspberry and hifiberry but now the big question:
Which raspberry and hifiberry hardware to I need?
