depends, some radios have an aux out and some bluetooth speakers have an aux in, if you have a random headphone cord laying around you could try it.

It's probably possible to build your own, but I really doubt you'd be able to just take apart the two existing (presumably store-bought) ones you have and put them together.

@HuskyDynamics01 i can buy new one but I want something that im build it's like hobby i guess, i also do same thing to food i can buy a pizza but i rather make my own pizza

@HuskyDynamics01 i found the yt videos that do a hybrid between Bluetooth board and radio board

@AndrewsGarsion Yeah, that's not something you can do unless they're both, like, on a Raspberry Pi or something that you could just rebuild one on the other board. Companies generally don't make their hardware in a way that lets them be combined in a modular way with others.

@HuskyDynamics01 nah dude 😂 i mean put the 2 modul/ motherboards become 1

Well, you can get one that does all three (I have a Sony one that's pretty nice and works great), but if you want to combine the two you already have, I'd suggest duct tape.
