Question about Alpine CDA-9855 CD Player

Open Question

Won't play music out speakers

The cd player will turn on and you can use all of it's functions but when you have a cd in it registers the cd and acts like its playing the cd but no music comes out the speakers. the preout out puts work fine for hooking amplifiers but the speakers have no power at all. the cd player is in an 88 mustang cobra GT, i've checked fuses and all with a test light to all the wiring too. the manual says that the "power ic" option turns it on and off but it still won't work either way. your assistance is greatly appreciated

    i have the exact same problem it was working fine in my Lexus Es300 however i went to put it in my Mountaineer 2000 with an aftermarket radio and everything works but the sound. Keep in mind my other radio works fine,so i have to use the old one until someone figure this little mishap out.



    Thanks NewYork

SOURCE: Alpine car cd player has no volume

It's possible that you have a shorted speaker wire. If one of the speaker wires is pinched, grounded or shorted it will cause the deck's internal amplifier to shut down. The easiest way to check is with a multimeter's resistance function. Remove the CD player and unplug it. Set your multimeter for "resistance" or "continuity". Attach the black probe to chassis ground; you can use the black ground wire in the deck's harness, clean dash metal, or the outer ring of your cigarette lighter. Use the red probe to test each of the speaker outputs in the harness: white, gray, green and violet. If you find a speaker wire that shows any continuity with chassis ground, then that's the cause of the problem. A speaker with a damaged voice coil may also cause the deck to shut down. To test this, probe the positive and negative leads of each speaker and test the resistance between them. For example, to test the left front speaker you'd put the red probe on the white wire and the black probe on the white/black wire. Each speaker should read a minimum of 3 ohms of resistance. If you get a lower reading then it might be causing your problem. If you don't find a problem with any of the speaker wires, then chances are the deck's internal amplifier has failed.

SOURCE: alpine 9881 cd will not play sound

If you had to connect the remote amp turn on lead from the headunit to the factory amp turn on lead you may find your problem there.

On many headunits there are 2 blue remote wires 1 for antenna and one for amp turn on. The antenna remote only supplies power when the radio is playing not when playing CD's. If you hooked the antenna wire to the amp trigger then the amps shut down when you play a cd. If that's not it let me know and I will research further.

SOURCE: Alpine CDA-7873 (Same as CDA-7876 basically)

the blue line from the radio harness does not have power when the cd or aux are being used and the amp is not turning on-wire the remote line from the amp to the red line and your amp will stay on and you will get sound

SOURCE: radio sound but NO cd or ipod sound

its not the radio. you have an amplified system in your vehicle and you hooked up the power antenna (blue wire from the radio) and the amp is only energized during AM/FM playback. disconnect the blue wire and connect the blue/white to the car's harness to energize the amp during ipod and cd playback

Everything is working including registering music on the display but no sound out of speakers,


You would probably need a separate amplifier for the speakers because the unit does not include one.

Location of reset on unit


when you disconnect it from cables, it resets. But i believe that is not the problem. Check speaker cables. I think you have problem with internal power amps. They have thermal and current protection. look for short circuits on speakers or speaker cables.

Amps wont stay on


try to look at the connection on the back of the cd player and make sure that the amp power wire is connected to the power wire on the wire harness on the back of the cd player and that should work but i only need one amp for a pair of 6by9s and subs try to bridge the speakers all to one amp that should cause it to sta on while in cd mode hope that helps

Don't play any music


Is there an orange "dimmer" wire missing? I found out the hard way,
using and older harness, that it needed an additional power wire.
If I remember correctly, it goes in directly under the ground wire,
in the next row.
Hope I helped
