Audio Systems/MBZ Bose System Problem

Expert: - 6/9/2007


Question
I have a 94 SL 320 w/ the factory Bose sound system (Alpine head unit and CD Changer).  The problem is... about a week ago, I turned the stereo on, the antenna did not raise and I have no sound coming from any speaker.  The stereo powers on normally and does not read out any errors.  I checked all the fuses I could find... 2 under the bonnet and one fuse on the amp and all look OK.  Can you give me any suggestions as to what could cause this?  Again, head unit turns on acts normal but NO sound from anywhere and antenna does not raise when stereo is powered on.  This is a first for me so any info would be greatly appreciated

Answer
whne the raadio turns on it sends power out 12 v for the antenna and 12volts out to turn on the bose amplifier in the trunk

it looks like the radio is not sending the power
radio needs to be repair  this is not a normaal problem and it only happends when you try to add aditional amplifiers

radio is made by alpine ,any alpine service center will have the parts and know how to service thi head unit
