Please help me with this mini-project.
I want to build a small audio system for my Bajaj 4-stroke motorcycle taxi, and the system consists of the following: a small Bluetooth module, an LM2596 DC-DC buck converter, an HX-A901 preamplifier, and an XH-M543 amplifier. And some small speakers with no more than 40 RMS. I had forgotten that I planned to put a 1000 uF capacitor between the Bluetooth module and the regulator, and another 4700 uF capacitor at the amplifier’s voltage input. And finally, everything would be powered from my motorcycle’s battery. (I put this together using ChatGPT since it’s my first project and the components are imported from China.) The main thing is that I want music but don’t want to feel like I’m in a sound car, and I want components I assembled myself—and affordable, of course, since I don’t have a budget. I’d like to hear your opinions, and please excuse the poor quality of the images; one was made by me and the other by AI.
