you can drive 11 stereo pairs off one 70v amp if you install transformers at each load. otherwise, you're looking at a dedicted stereo amp for every 4 pairs maximum, assuming that amp is happy driving a 2 ohm load. perhaps one six channel surround amp with 4 speakers/ channel would get it done, assuming you can find one that's stable at 2 ohms per channel. try searching on Audiosource amps and racks for an affordale multi-channel install system, partsexpress.com carries them I believe.
