This "Hauss Medua Labb Speaker System" is it just a set of bare-wire speakers, or there's also a device where all these speakers connect to? There's not much info online about that system, so couple of pictures (or links to website) would help.
What are exact model numbers of your Kenwood and Sony?
The Hauss speakers seem to be self contained self powered HT systems. Not much details online.
You could connect the satellite speakers directly to the receiver speaker terminals. The main unit/sub could be connected to the subwoofer output of the receiver. Use the remote of the Hauss to set the subwoofer level,
