hi Ben my name is Matthew Pownall and I would like your help with a build I am trying to make as I am New to PCB, I am trying to make a portable speaker box for camping or use it in the back yard when having a BBQ, I live in the UK, this requires one mini 3 watt-10 watt amplifier, a few full range mini speakers, a battery, audio input from any device with a head phone plug input (AUX or micro SD card slot) and maybe a solar panel to charge it when i'm out and about plus a charge port to charge the battery. Thank you very much. p.s. this has to have great sound quality and a good volume level for everyone to be able to hear it. also I was wondering if you could build one in a video for me
