This won’t work well. The Arc already contains the L, C and R channels.
You could add the Amp as a separate ‘room’ and group it with the Arc, but although it would be in sync for music it would lag behind the Arc for TV content via the HDMI, giving rise to an echo.
OK - is there any way to keep the old fashion HECO speakers and add ANY Sonos bar in the same room? Thank you!

No.
you can add any speakers into a group. The “room” name is just a label for ease of identifying a particular speaker/speaker set, so you could, for example, have an Arc/Sub/2xOne’s as a Home Theatre arrangement and physically have a pair of Fives in the same room for stereo music-playing duty. Or an Amp could drive your existing speakers. But as already said, if you then grouped Home Theatre with Music there’s be a delay on the TV source to the Music speakers. They would be in sync for music though.
Hmm… OK! Thank you for your quick help.
