It has to do with power fluctuations. Since the Bluetooth receiver and some part of the amplifier are digital, the power drawn can change very quickly. This would result in a voltage drop, which can be audible. To counteract this, you can place a capacitor in parallel. This will supply the extra current when necessary (voltage can't change instantaneously in a capacitor).The value itself doesn't really matter. Make sure the rated voltage is higher than what you connect it to. Best is some different values parallel (frequency that is most blocked\absorbed depends on the value, so more values = better coverage). I have 4 ranging from 470µF to 1nF or so. This was because my system had too much noise, but it was another Bluetooth module.Hope to help :-)
