I put in a cd player everythings connected but there is no sound coming out of the speakers

either your connectors need cleaning or maybe a break in the wiring. Is there on spot where both wires come together if so check there.If there is any plugs, pull them apart and clean them with contact cleaner

Unscrew the suspected speaker and use a DVOM to check that values are correct or???......Check for juice at the + terminal of speaker with radio on,probably a open circuit,check your grounds....It is possible the output is completely fried;will appear that everything is okay,but no output......

I ran into the same problem with my mustang. Your vehicle uses a common ground for the speaker wire. Modern cd players have a safety mechanism that cuts power to the speakers if an improper ground or short is detected. Run new speaker wires to your speakers. Make sure you don't run a screw through them when putting everything back together. Just one speaker wire shorted out will kill power to all four speakers.

So everything is coming on but you have no sound from anything?If that is the case you may want to check the amp fuse.The car has a factory amp i'm trying to remember i think it is in the trunk.Look in your owners manuel for the fuse box location.If the fuse is good then the factory amp may be bad.Or you may have a blown speaker that is showing a short and putting the amp into protect.If the amp and or speakers are bad i highly recommend just buying after market speakers/amp.The price for the factory equipment is very high and there labor rates even higher lol.Plus if properly installed you will noticed better sound from the after market stuff as long as you get brand name equipment.Go to a well trusted audio shop in your area they should be able to see if it is a speaker or amp problem if your fuses are all good.They should be able to test the impedance of the speakers at the amp for you and see what is going on.

If you got the stereo used the speaker wires might not work. I stereo only puts out sound thru the RCA output using an amplifier.

DOES THE RADIO PLAY? HERE ARE THE FACTORY WIRING COLORS FOR THE RADIO HARNESS, RECHECK YOUR WORK. IF U FIND NOTHING THEN IF THE RADIO PLAYS THE CD PLAYER IS DEFECTIVE, IT HAPPENS BELIEVE ME.

Is your IP Bus cable on the INPUT and not the OUTPUT ? I know it sounds funny, but usually(95%), that's the case. If it's in the wrong plug, you'll have power and a display, but no audio. That's why your getting data but no audio.

Some high-power players have an internal fuse in line with the speakers so that an external short will not blow the output transistors. Have someone skilled look for this.

Also, check that your speakers are not wired backwards; some speakers will connect one side of the voice coil to ground. If you connect the hot side of your CD player to the ground side of the speaker, you kill the sound.

hot at all times: blue/red
hot in acc or run: blue/black

this is for factory am/fm stereo non premium sound

On many cars there is an exterior amp that the sound goes through before it is sent to the speakers. If the remote turn on wire isnt connected after you take your previous cd player out then the amp wont know when to turn on and therefore no sound will come from your speakers although your cd player is doing its job.
