With a set up as such, one does not have to worry about keeping the impedance matched throughout their music system as they would on an 8 ohm based system. Impedance is a measure of resistance and in a 8 ohm system if you hook up too many speakers to one amp the impedance will change to dangerous levels and potentially destroy the amplifier. However, you can wire these in parallel because of the transformers spoke of earlier, which again regulates the wattage. To calculate the wattage of the 70 volt amp needed to run your system, simply take the total wattage of all the taps and include a 20% buffer, just to be safe. Moreover, all the taps do not need to be set at the same wattage, hence, you can thereby set the volume for different location when the amp is at one constant volume.
