Hey guys I'm looking for a home theatre amplifier, in specific for a cafe.  I have 4 speakers installed in the cafe with 4 wires that go to an amp however I am having trouble finding the right amp.

The amp needs to be iPod/iPhone compatible so I can play music through my iPhone, it also needs to have a FM radio, can anyone recommend a decent or low price amp for this use?

Thanks for any help in advance
