Tpa3116d2 output filter advice

I recently ordered a set of what seem to be xm-m562 tpa3116d2 boards to use in a project. My reason for choosing these was that they don't seem to have any output filter, allowing me to build my own using parts I choose. I was wodnering if anyone had any advice on inductor and capacitor selection for this. I am going to be setting up two of them as stereo amplifiers, and one in BTL for a subwoofer. Any advice would be appreciated! At the moment I am looking at these for the output inductors:
MGV1004100M-12 Laird-Signal Integrity Products | Inductors, Coils, Chokes | DigiKey


One other question I have is if anyone knows what the gain setting is on these boards.


PS: I'm new on the forums. If I've made a mistake in where I'm posting this, or if I should have simply posted this to an existing, thread I'm sorry.
