Output Power of Audio Amplifier
https://amplifier.cd/Tutorial/Power/output_power.htm
DC voltages is not possible. 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 …

DC voltage on both channel outputs is -25mV, but uPC1237 keep relay closed and there is no signal on output. BIAS is 15mA and has no influence to DC voltage on output. Any suggestions on where to go from here would be appreciated. Attachments LM4702-100W-2-0-kana-klasy-AB-p-yta-wzmacniacza.jpg_q50.jpg 64.2 KB Views: 77 AlbertHall Joined Jun 4, 2014

https://www.nxp.com/docs/en/data-sheet/TDA7053A.pdf
The TDA7053A and TDA7053AT are stereo output amplifiers with two DC volume control stages, designed for TV and monitors, but also suitable for battery-fed portable recorders and radios. In conventional DC volume control circuits the control or input stage is AC coupled to the output stage via external capacitors to keep the offset voltage low.

A DC amplifier (direct coupled amplifier) can be defined as is a kind of amplifier where the one stage output of the amplifier can be connected to the next stage input for allowing the signals without frequency. So this is named as the direct current which passes from input to output.
Are Speakers AC or DC? Here’s The Truth – Stamp Sound
https://stampsound.com/are-speakers-ac-or-dc-heres-the-truth/
Divide the AC voltage by the square root of two, and this will present you with the DC voltage. You can input this equation into a calculator to ensure that you get the right answer. For example, if the speakers have an AC voltage of 60V, you would input 60/√ (2) which would give you a DC voltage of 42.42 V.
