DIY Speaker kit help


Hi.


Wondered if someone would be able to help me. I'm looking to convert an older wooden box single speaker into a unit that can house an Alexa device and speakers within it. I'm looking for a simple 2 coaxial speaker kit or order separate components so it can all be housed within the unit, and attached to the Alexa via the 3.5amp jack. I'd look decent quality speakers. But thinking under £30 seems possible?. Would anyone know where I could get these bits. Ideally would prefer not to have to solder


Thank you for any help, Dave

Hi. Thanks for the prompt replies. If I go for the amplifer board. I guess this needs additional bits such as power and looks like it needs an antenna too, is that right? So coaxial speakers come with wires attached and would it realistically need a separate base? Thanks again
I've found this but it's not mains powered and not sure how good the output will be?
