You want to put the TLV320AIC3204 and TPA3007D1 in a box, and have a cable run 100 m to a second box containing the speaker and the mic?
Is my understanding correct?

Sorry, this is a somewhat unusual application, so I'm afraid I won't be able to offer you any concrete recommendations.
I think one thing you can be sure of is you need to put a mic pre-amp at the box end, and even then, your mic signal is probably going to be corrupted by the noise on the speaker wires from the class-D amp.
You will need some serious filtering and isolatino in your system...
Noise is a little tricky... You can try better shielded wires, RC filtering on the cable, DSP filtering, etc, etc.
It's very system-dependent, so you're going to have to test different things on your system to see which is most effective for you.
