I just moved into a place that has two in wall rear speakers, another two behind those in the kitchen and two outdoor speakers on the patio. Needing help with the setup. If I have the arc connected to the tv via eARC, does the AMP need to be connected to tv as well or will communicate wirelessly with arc sound bar? Also, unclear on how to connect the speakers. Do I need multiple AMPs? Plan on simply playing content from tv in living room and kitchen and occasionally on the patio. There are volume controls on the wall for kitchen and patio. Thanks.
