I dont know much about amps and DB and such, but what i do know is i want to build a speaker.
I was thinking of using a tda7492p circuit board. And a 52mm 4 ohm 5 watt speaker. The power supply i was going to use is a 9800 mah 12v DC. Im not sure if this is a combo. I want the speaker to last to 20 hours of battery life and i would like it to be as loud of 92DB. Will these components be a good combo? Or will i need to switch some things out?
