It wasn't too clear if you are intending to run speaker level audio (ie, from the amp to the speaker) or line level (ie, from a source to a receiver / amplifier in another room).
For interconnect level distribution you can use Balanced Line Drivers without degradation over 1000'. Running from the amp to the speakers over phone wire is, well, pot luck. It may indeed provide enough quality for the intended purpose. In either case, you must use care in selecting the right wire pairs to avoid equipment damage. Who knows, you may achieve the added benefit of "music on hold".
