Capacitor Selection for Coupling and Decoupling …

This allows high frequency signals such as AC components to pass. In audio systems, DC sources are used to power audio circuits. However, since the audio signal is usually an AC signal, the DC component is unwanted on the output. To prevent the DC signal from appearing on the output device, a coupling capacitor is added in series with the load.

Output Inductors. Adding a small inductor in series with the output of a power amplifier may sometimes be necessary to ensure stability of the overall feedback loop with a range of capacitive loads. The inductor plus capacitor load then form a series resonant LC circuit which can have a very small total series impedance at the resonant frequency.

it is necessary to keep this high frequency energy from entering the chip in the first place. This is generally done with a combination of electrolytic capacitors (for low frequency decoupling), ceramic capacitors (for high frequency decoupling), and possibly ferrite beads. ... especially when op amps are driving high output currents. When a
Output Power of Audio Amplifier
https://amplifier.cd/Tutorial/Power/output_power.htm
Most audio amplifier does not transfer DC voltages. The background for it is that a woofer coil can be easily destroyed by DC voltage, therefore is in such a way designed the amplifiers that DC voltage is not amplified. Meaning of the output power for an audio amplifier

The new HF decoupling will be just as bad as the previous. The HF decoupling must be located at the output devices and connect to each other via the shortest possible loop. That common Power Ground is then routed to the MAG. The power should come into the fuses and go to the reservoirs. Then from the reservoirs to the Drain feeds.
Taming the LM3886 Chip Amplifier: Power Supply Decoupling ...
https://neurochrome.com/pages/supply-decoupling
Power supply decoupling is critical for stability and performance in audio amplifiers, incl. LM3886-based chipamp and gainclones. The decoupling network recommended in the LM3886 data sheet is simulated and a better decoupling network is suggested. The effects of the PCB layout are included in the simulations.

The output of the LM386, like most power amps, contains the familiar R-C ( Zobel ) network connected in parallel with the speaker voice coil. I recommend adding this to all PA output stages. Since a speaker load presents a complex impedance, placing the Zobel network in parallel with the voice coil keeps the amplifier happy since it’s a ...
