Make the LM386 circuit that is in its datasheet.
Its minimum supply voltage is 4V where its output power into 8 ohms at clipping is only 0.07W which is almost nothing. You are powering it with less supply voltage so if it works then its power will be less.
It won't have interference if it is built compactly on a pcb and the input cable is shielded audio cable.
