Bob: the Shamrock 19 is not a very large unit - inside there are only 2 speakers - there is 1 speaker above the couch and 1 above the dinette. I am hoping to have 2 speakers at each location instead of 1 ... How many ohms rating do I need for 2 little speakers
FR seems to wire the speakers differently than you may think.
A controls 1 speaker only (gotta be mono)
B the other. mono too I guess.
C controls the 2 outside speakers. Maybe stereo.
I wondered if FR was running 4 wires - for 2 speakers - even though it connects to 1 speaker ??
PS: I'd love to see the wiring diagram (if different than the manual) and the back of the unit pic - the manual is very blurry and you cannot read the legend for the rear connectors.
