Raspberry Pi with more Than one amplifier

I’m trying to look at providing output to multiple room. But I don’t want multizone

So I’m wondering if I could stack multiple amp hats on top of each other, and if volumio could drive multiple amps via gpio

So was thinking of an enclosure with a couple of amps

Any ideas? I was hoping it could all stay in one box rather than separate pieces of hardware with separate power supplies

This seems more a question for the particular amp hat manufacturer. One complication would be how to source power for each of those hats, all connected to one RPi.
