Thanks for the good explanation. I learned alot and have alot to learn.
Alot of times I'll just get 5W or 15W class D amp boards https://www.amazon.com/Ximimark-1-8-12V-TDA2822M-Amplifier-Channel/dp/B07KC1CZWY/ref=sr_1_4?dchild=1&keywords=12v+amplif…
I cant build them nearly as cheap as buying them.
I have built LM386 boards and 5V relay cards, once, then found just the parts cost 2-3X as much as buying a prebuilt surface mount one.
