There is not fuse or replaceable component in the speakers, they either work or they don't. Whe nthey don't, throw them away and have fun picking out a new pair! [img]/infopop/emoticons/icon_wink.gif[/img]
As for the radio not working at the same time, do you mean not working with those speakers connected? Or have you tried to connect a different pair of speakers to it? Does the display on the Radio light up?
My guess is this: Your radio does NOT light up at all. Also, your speakers do not work at all even conected to a different radio. If that is the case, you need a new radio AND a new set of speakers provided you have checked the fuse on the radio circuit. Most likely, something shorted in the radio which in turn, "blew out" your speakers with a surge of power.
Good luck.
