Thinking of making a pair of active speakers with these modules, and I have a couple of questions I was hoping someone could clear up:
- Would it be OK to place them inside the enclosure with regards to heat?
- Some of the mounting points on the boards are meant to go to ground (e.g an aluminium enclosure etc), while I was thinking of mounting them directly to MDF or a plastic board. Is this a problem?

Well the datasheet says it has thermal cutouts on both the power supply and the amplifier section...
Without knowing the size of the enclosure its hard to guess - the datasheet has some specs on dissipation at various test signals, notably 1/8 rated power pink noise, which I think is meant to represent typical music signal. However for a subbass this isn't really representative.

It's probably doable, but it also exposes the module to a lot of vibration. There's some protection (silicone on some of the bigger parts) but there is still as risk that it shakes something loose over time.
To be honest I wouldn't do it if you have the option of adding a partition of some sort, even a fairly thin one.

It's a medium sized bookshelf speaker. I'm thinking the port will help with heat dissipation.
Probably an issue for a sub, but for a small bookshelf I can't imagine this being a problem 😉
Sorry, I somehow managed to confuse myself into thinking you were building a sub - not sure why. Yes, for bookshelfs i would agree 😛
