I have a friend that recently bought a house that was already wired for speakers out back. He has a lower deck and upper deck each with a pair of 8 ohm speakers connected to a volume control knob in the zone. Both sets have a 2 pair cable that runs inside to a four post banana plug on the wall where the receiver will be and are obviously wired in parallel, but can easily be separated at that point.
The questions are:
• Since this is setup as 4 ohms is it OK to use on a zone 2 from a mid-range receiver and is this smart to run this way in general?
• Will the volume knobs in each area pose a problem for the receiver?
• He is thinking about a third zone to drive two speakers in the house, what receiver would be good driving 5.1 plus two other zones in the$ 500-$1000 price range?
• He will want to run 5.1, plus zone 2 and zone 3 simultaneously with zones 2 and 3 as either the same content or different.
Thanks a bunch for the help!
