I see that there are speakers that play notes when hooked up to terminals but can they be hooked up to radios to play the music louder? I cant try it untill I find more copper untill then is it possible to play radios louder?

By louder I have to assume that you mean hear them at a greater range. There is a volume slider in the audio options that will allow you to make the radio louder than everything else(by turning them down and your desktop up) but no I don't think we can adjust the range.

Ya i meant range I installed a jukebox and would have like to have it played through out the settlement.
