In general I would prefer independent power supplies for each channel resp. for each module. So you can better handling the GND management.
For your application this means an outdoor power supply.
Additional I would use for each module an own screened (e. g. aluminium) enclosure to avoid inteferences between the mudules in the kind of this one:
1590B | 1590 Aluminium Enclosure, IP54, 111.5 x 59.5 x 27mm | Hammond

Check out post #2 under
Sanyo/B&O Icepower 200AC Rev.D, schematic about rev. engin., not complete finished
Maybe your modules are similar and the schematic is helpful for you.

Now an off-topic question.
I want to know the for me unknown manufacturer from your country of follow class-D modules:
"DS-15" and "DS-300" - check out the URL
DS-15 Class-D Modul with much Trouble and used in a lot of Models from Harman//JBL
Maybe you can ask or find any informations on threads from your country like
?DIY? - Powered by phpwind
and
DIYPlus • ??.
Thank you very much for your efforts.
