Hello, I've made a portable speaker... weird one
2x PAM8403,
powered from USB,
2x fullrange speakers 5W,
2x cheap 4ohm tweeters (because these fullrange were more like low tone),
and 1x 20W subwoofer speaker 😀 ( I know it's underpowered, but it was meant to be powered from 5V powerbank)

I did not connect any capacitor or resistor on USB in, should something be there?
