So why not build your own? Here is a DIY video by GreatScott! on making your own low budget bluetooth music system.In this video I will show you how I combined an old speaker of mine with a cheap bluetooth receiver module.
I made a small power amp for the speaker and put all the electronics in a hidden place. I hope you enjoy the video.

The main focus will be on designing a low cost audio amplifier circuit around the LM386 and the NE5534. The bluetooth receiver costs 4,5$ and the audio amp 3$. So you can call this low budget.
