Go to a stereo store or Radio Shack, etc. Ask for a speaker splitter that allows one feed from your amp/cd stereo and then 4 or 5 jacks that can be switched on or off. Divide the house into 5 zones. Label the speaker wire pairs by finding out which goes where, then plug the appropriate wires into the zone you want them to be on.
Zones:
Living Room
Kitchen
Exterior
House
Bathrooms
or such, depending where the speakers are located. You can also feed a satelite radio to your amp; which is what I have in my home; I love it and you will too.
Cheers,
