Awesome builds! Really considering building something like this. I am a bit skeptical though, how are these cheap Chinese amp-modules holding up over time? Also wondering what kinda speakers people are using, and is it 4 Ohm or 8 Ohm?

I found a version of the module where the heat-sink is screwed on, since I saw someone had problems with them delaminating. It also has a huge through-hole filter cap that I could just swap right away to some top quality brand, as long as the solder pads hold up: https://www.aliexpress.com/item/4001290053519.html

I see Pedalpcb is coming out with an amp-module I could upgrade to later. Probably higher quality, but it's using the TPA3118 version which does not have a heatsink, instead the heat is dissipated through the bottom of the chip and to the board, probably why it's also lower rated at 60W: https://www.pedalpcb.com/product/tpa3118m/
