Question about 2001 Mercedes-Benz SLK-Class

1 Answer

No sound from Bose speakers

Same problem as another poster.

I don't know what is meant by check #14.

Previous poster's submission (exactly my problem)....

The car battery went dead and after it re-charged, I entered the code to activate the audio system. All buttons started to function properly (stations, treble, base, etc.) except the speakers produced no sound. The volume button seems to work but no sound is coming from the speakers. What can I do to fix this?

This is a very complicated system.There is a system called a d2b ring-it is a fiber optioc loop consisting of your amp,phone(if installed),c.d. player(if installed) and the voice activation module as well as some tele aide systems in certain models. Your head unit wakes these components up during start up of the audio system with this fiber optic loop. If the head unit is not coded properly( I mean version coded not security coded) It will not wake up these components. If any of these components are damaged they will not return the wake up signal back to the head unit or to the next component-depending on it's postion in the loop. The first thing I would check is if any other components work(if you have them) obviously you will not get sound but you will get visual confirmation from your head unit. Next see if the fuse is blown on your amp.it should be located in the trunk behind the trunk liner(i beleive it is on your driver's side). Next find the fuse for your radio head unit in the fuse box and remove it.(make sure the key is off). Wait approx. 5 min. to drain the capacitor and reinstall fuse and put in your security code. If all these tasks fail to restore your sound take your car to a shop and have your command(audio system) version coded and scanned to make sure you do not have a faulty component. I hope I have been helpful.

Hi, my Bose sound system in my Mazda 6 luxury sports hatch 2008 model all of a sudden has no sound. We have checked the Bose fuse and it's not blown. I have power to my radio it all lights up


Bose sound systems have an amp board mounted to each speaker the rear 6X9's should be the easiest to check. power and ground should present at all time with the car on when radio is then turned on you should see a 12v signal voltage another wire in the plug at the speaker. My guess is that 12v signal that comes from the radio is not functioning and the radio needs service.

Rear deck speakers don't work


Nissan's 2008 Altima was offered in several trim levels, ranging from the base 2.5-liter four-cylinder model to the sportier 3.5-liter V-6 Coupe. While the high-end trim levels were equipped with a premium Bose-developed nine-speaker sound system, lower-end Altima models were fitted with a standard six-speaker system mated to a single-disc CD player.-------------------------------------------------------------------------------

Installed a Sony Xplode into a 99 Blazer and everything on the radio works but will not play through the speakers


The Bose system is complex - it has an amplifier separate from the Bose compatible radio. This amplifier takes low level audio signals from the radio, not full driver outputs from a replacement radio, and by trying to use the replacement radio you may have blown the amplifier. If that is the case, you may not be able to go back to the original radio.
The only option you may have with the replacement will be to find the Bose amplifier and bypass the connections to feed the replacement radio outputs directly to the speakers. This may not be as simple as it sounds, as distribution to the various speakers comes from the amplifier, not the radio, and the wiring from the amplifier to the radio may not have all the wires you need. Before going on, you had better get a wiring diagram for the Bose system (service manual or Alldatadiy.com).
