Explanation of LED Screen's configuration

Interesting radio. They come with separate LED screen sold? And USB sick. I’ve never seen that radio before. By G u mean hertz, as in mega hertz connections? Right? The only thing I have on a radio like that is the USB. That’s a high potential zone. As in NPN and PNP bipolar transistors. Not sure how they connected a stick to it to input music. Reason being the OP AMPs buffer area still has only two inputs to it. Not three. So I don’t how they designed this radio. It’s not physics, just not the appropriate tech yet. Walmart sell those as a separate unit. And maybe auto-zone. You can hook up Bluetooth speakers to it. I’m not sure if they have the inverter for iPhone Car charging on USB. They all come with a cigarette connections to that inverter. But that’s the USB. Still there. Remember current flows from a high potential area to a - e low potential area zone. - e flows in the opposite direction direction.

I think lots of people like car audio and want to learn it. I’m all for the trade. But I’m for the old school bead board guys testing their designs first before it comes out on the market. This technology hasn’t come out yet.​

I can see your point. At 128 G that may require more power. If so, some thing that will convert the ampere, 1 ampere or 100 ampere, to 10,000 mA. But I would not know what component or how to even design this circuit. But the design is already there. Able to work.​
