I had a house built last year and knew I wanted a whole house music installed but the money ran out doing upgrades to other areas in the house. Here is what I now have: speaker cable ran to ceiling locations in kitchen, porch, and master bathroom, cat5 and speaker wire ran to future keypad/volume controls (have a blank wall plate over the holes)and speakers installed in the ceiling in the greatroom using an old receiver. I had the cable bundle pulled to a cabinent in the greatroom thinking I would use a receiver to power all speakers but now I have been reading that the receiver's amps will not power all speakers (four pairs). I cannot think of a time when all will be in use at the same time, maybe three out of the four though. Any ideas or personal experiences would be helpful.
