How does it work| Amplifier mode| what is the bridge mode in power amplifier

A long time ago, I made the same video but it is noisy. Today, I decided make another video to replace it as I promised. Hope you like it!
By default, the power amplifier has 2 channels. They are often called the left channel and the other is the right channel. To feed the signal into 2 channels of an amplifier, we have some ways such as balance cable, and RCA cable. I fed the signal into two channels of an amplifier by an RCA cable. The left signal from the RCA cable is fed into the left channel. The right signal from the RCA cable is fed into the right channel.
Two channels separately amplify each signal, so that, you hear two dissimilar sounds that appear at two speakers. That is the stereo mode.
In parallel mode, the input signal only uses the left signal or right signal to all of the channels.
Suppose that the left signal is fed into channels, so that, the output signal of the left channel is the same as the output signal of the right channel.
You don't hear the difference between the two channels. That is the parallel mode.
In bridge mode, the input signal is the left signal or right signal. Assuming that the left signal is used, again. The left signal is fed into the left channel of the amplifier.
At the right channel, the signal left is inverted before it is fed into the right channel of the amplifier. At output terminal connectors, you will see two signals inverted phase.
If an oscilloscope is connected to two red terminal connectors, you see a double signal. In bridge mode, the speaker is connected to two red terminal connectors.
