If the audio sound is not output, the radio and
CD player may have a problem. In addition,
if any of the speakers or tweeters is short-circuited, the protection
circuit inside the radio
and CD player disables all the speakers or tweeters to sound. Therefore, if
all the speakers
do not output sound, the speaker or tweeter circuit may be shorted or the
speaker or tweeter
may be defective.
