The volume control is supposed to be logarithmic so the amplifier begins to clip when the signal is high and the volume control is set to about half-way. Then low signal levels can be "turned up". A logarithmic volume control at half-way attenuates the input signal 10 to 20 times.IIRC the ipod output level is some 30 times the level needed to drive the amp at max volume.
If you find, using AG's simple circuit, that the volume control always has to be set near the minimum then you could add a 47k (or thereabouts) resistor in series between the ipod output and the 'in' terminal shown.
