There are a lot of people talking on this topic and it has become very complicated. Wiring of two channels on one speaker is possible but in many ways, it can damage your amplifier.
You may be trying to run both the left and right channels on one speaker only. It can be done but method may vary from setup to setup of the amplifier.
Now we discuss some methods that people are trying to wire both channels on one speaker and tell you whether it will be good for you or not.
Wiring Left and Right Channels Together
Many people tried this by connecting the left and right channels together and then connecting them to the single speaker. First of all, keep in mind that it is a parallel circuit and the current will be the same. You are not going to get any advantage from it.
The quality of your sound will not be affected by it. Rather than getting good, it is possible that your sound quality becomes even dull.
Both of the channels will fight each other. Your amplifier may get hot and cause damage. So it is not possible to connect both the channels together in this way.

Mono Switch Method
You may know many old amplifiers have a MONO switch on them that let you connect one speaker to 2 channels. This could be a safe method to use for this purpose.
You can make a MONO switch yourself if it is not available in your stereo.
This is another method that most of the people are using to connect both channels.

These are some types of methods being used to connect two channels with one speaker. We do not recommend you using any of these methods.
The best strategy is to get one more speaker and connect both speakers on both channels. If you want to run a single speaker, you should connect it on one side and that’s all, don’t change anything else.
And if you still want to connect both channels to one speaker, use the MONO switch method. If not, use the bridge method.
