System configuration Confirmation

I just want to confirm that I am going to get the correct parts for a build. I plan to set up a Squeezebox Player to drive a pair of Polk Atrium 8 speakers:

Power Range (watts) 10-125
Impedance (ohms) 8

Would a Raspberry Pi 3B or 3B+ work or should I go with a 4B with more memory? What about a Raspberry Pi zero? Sorry, but I ado not know how much the Pi is doing as far as processing.

Also, would I pair it with the HiFiBerry Amp100 or would the Amp2 be all I need? What if I also wanted to drive a sub?

I understand I would need a 12-18v power supply. And if putting the electronics outside, a waterproof enclosure. I currently intend to have the electronics inside.

Is this all that would be needed?

Think you for your time.

Kindest Regards,

Hi,

I would not recommend a Pi Zero. It's very slow. A Zero 2 works better, but even there the missing Ethernet can make configuration problematic. If you loose WiFi connectivity, you ca't access the system anymore. For your speakers the Amp2 is probably powerful enough.
If you want to drive more than 2 speakers (e.g. an additional sub), the Beocreate 4-channel amplifier is the only way to do this.

When putting things in a fully closes enclosure, make sure it is big enough not to heat up too much. This can be especially problematic if you use it during the summer and sun shines directly onto your box.

An 18V or 20V power supply (like the HiFiBerry power supply in our shop) is recommended.
