The amplifier circuit diagram shows a 2.5W * 2 stereo amplifier. You can also make a 5W mono amplifier out of it. (Check out the TEA2025 datasheet for more information on that) On the input side, you should use a dual potentiometer. A dual potmeter allows you to connect both the left and right channels on one potentiometer.
