Coupling & Bypass Capacitors
3.3 Power Amp Bypass Caps. Power amplifiers are generally comparatively low speed, but bypassing is almost always needed unless the amp is only millimetres from the power supply. It is fairly common for power amps to use bypass caps ranging from perhaps 10µF up to 220µF or more, and these are often in parallel with smaller caps.

Does capacitor upgrade on amp really improve bass? :
The goal is to keep the power supply up & amp not clipping throughout the rated range of operation for the amp. So the greater the power the larger amount of capacitance, it needs it. Adding more* to a low power amp does little as the amp can only put out so much. It may have an effect at the extremes of operation (volume @ 11) but likely not

6 FAQs about [Which capacitor is best for power amplifier]
What are the best capacitors for audio power supply?
For the best capacitors for the audio power supply, you can choose any of the capacitors we mentioned in our article. Audiotek 5.0 Farad Capacitor Car Audio 5000 Watts Power 12V Car Digital Power Digital Red 3 Digit... 5.0 Farad Capacitor Digital Red 3 Digit Voltage Display. Reliable and long last Stiffening Power Capacitor.
What are audio grade capacitors?
The audio grade capacitors are optimized explicitly for high-end audio applications. They tend to offer more advanced performance in audio circuits than standard components. Aluminum electrolytic and film capacitors are commonly in use in audio circuits.
What types of capacitors are used in audio equipment?
Ceramic capacitors are another popular type of capacitor used in audio equipment. These capacitors use a ceramic material as the dielectric, providing a reliable and consistent performance over a wide range of frequencies. Ceramic capacitors are often used in combination with other capacitors to provide a more complete filter response.
Why do power amps have a capacitor value?
Input, feedback and DC supply paths in power amps and preamps will always have a defined resistance, and the capacitor value is chosen to ensure that the lowest frequency of interest (typically 20Hz) is passed without attenuation.
How to choose a capacitor for audio processing?
For high-frequency signals (e.g., high-speed audio processing), look for capacitors with a low inductance (the tendency to store energy in a magnetic field). Another important consideration is the capacitance value. A general rule of thumb is to use capacitors with a value around 1-10 uF for decoupling audio signals.
Is a DC capacitor a good cap?
One school of "thought" claims that the best cap is no cap. This is fundamentally nonsense and extremely silly - there is absolutely no requirement for DC coupling in any audio amplifier. DC is a decidedly unwanted component, and invariably causes far more problems than the relatively small rolloff at very low frequencies caused by the capacitor.
