How to connect the speakers of two power amplifiers?

To connect the speaker, it is necessary to determine the power and impedance of the speaker first, and then make matching connection according to the output power and impedance of the power amplifier. Generally speaking, the output impedance of the power amplifier should match the impedance of the speaker, which can ensure that the speaker gets enough power and prevent sound distortion.

If two amplifiers need to be connected to the same speaker at the same time, they can be connected in parallel or in series. If parallel connection is adopted, the output terminals of the two power amplifiers need to be connected in parallel and then connected to the input terminal of the loudspeaker; If series connection is adopted, the output of one amplifier needs to be connected to the input of another amplifier, and then * * * is connected to the input of the speaker.

In addition, it should be noted that if the brands and models of the two amplifiers are different, it may cause sound distortion or interfere with noise.
