So if, for example, if I run line out of the home theater a/v receiver to the customer's old 125 watt marantz a/v amp, and then run this to the 6-way speaker selector, out to six rooms with non impedance vc's, each room should have ballpark of 20 watts or so, which should be more than enough to each room? Customer is not willing to spend more money right now on a dedicated 12 channel amp, or any other amp for that matter, and I, like you, after reading this post am leary of using the zone 2 on the main a/v receiver to power 6 rooms, 2 of which are outdoor locations which need more power.
