Default Possible to downmix ?

I'm not sure this is the right room to ask, if it's not, then perhaps someone will tell me where it should be ... or just move this post to the correct room.

I'm thinking about getting a small bluetooth streaming solution, but need some advice.
I am thinking about using one of these:
FREE shipping TDA7377 Stereo Audio power amplifier with KRC 86B Bluetooth module Car amplifier module-in Amplifier from Consumer Electronics on Aliexpress.com
and using it with some small speaker. Perhaps one of my old JBL SCS-178 satelites.
However, I really want a small solution, so I'm not planning to add 2 of those satelites, and since the reciever mentioned, is stereo, I will get some problems adding only one.
So the question is, is there some simple way of downmixing the stereo signal, so I get the full signal through one speaker?

Alternative I could use some smaller speakers, but small speakers with a decent quality would likely be a bit expensive, ... but if someone has good suggestions to what speakers, then I'm all ears.

Connect the signal feed left and right together, (if it is analogue), that will give you Sum signal - Mono.

Well, the souce itself will come through bluetooth, so I guess that wont be possible, but perhaps on the bluetooth module.

cheap speakers from Behringer.

JBL Control 1 look-a-like. I use them for TV, and are happy with them. Need a little eq at 80 Hz to get some oomph
