The following article discussing the implementation and application of RF filtering for car audio amplifier circuits. An audio amplifier circuit required to suppress RF interference produced by fast output transitions of the amplifier. This article is divided into following section: Introduction, Car Audio, DC Resistance (the DC resistance associated with the component reduces the power output of the audio amplifier), x2y Bypass Filter (showing application of a single X2Y bypass capacitor), Comparing RF Filter Performance, Portable Audio Devices and Conclusion.
