Hello we currently have a 100 watt sound system that has a few issues with the following

all ur work is on altium designer, so if you use altium it will be a plus.

-on off button always stay on

-audio output for headphone jack has noise.

-bass output wich is an independent amp has a few issues

- usb cellphone charging ports need to be 3 amp instead of 2 amp

- there is some interference when you put your hand close in some components, it seems like electromagnetic compliance issues
