We hooked up a cd player in my 2004 cavalier and have all of the wires correct but the only problem is when you cut the vehicle off the cd player dosent cut off with the car. When you cut the car off and take out the keys you have to push the power button on the cd player before it will cut off. Because we cannot find a memory wire i believe.
Brittany, you may have your radio’s switched wire hooked up to the constant wire. You have to run your radio’s switched wire to the ignition wire harness (orange wire) in your steering column. Hope this helps. Good luck.
which black wire is the ground there is a thick one and a thinner black wire?
After all the work taking apart my dash and installing my new stereo I’ve come across a slight problem. When I am driving and turn on my stereo it kills the power to my hud. Rpm, fuel, speedo etc all lose power. Why could this be?
*Addition, when my stereo is not turned on the hud works fine. And after installation I am stuck with 2 left over wires…purple and thin black
Mark, some late model vehicles require wiring up the dimmer and illumination wires in order for the dash lights to work properly. We currently don’t have the dimmer wire information but maybe some in the Modified Life community may be able to chime in. Hope this helps. Good luck.
i have the same problem with my 2004 cavalier as mark does and i cant figure out what to do with these left over wires. i have found that the thin black wire is just another ground, maybe for the dash lights not sure, and i was looking over your wire diagram for this car and there is no pink wire, atleast not in my car maybe mine just strange. anyway i was hoping you or someone could help me out. thank you
Your diagram lists only two wires per each rear speaker but there are four per speaker. Which brings me to my dilemma: I have replaced the factory speakers, front and rear, but the rear, which are 6×9, have four wires and I cannot find a wiring diagram anywhere to detail all FOUR of these wires.
the diagram shows only 2 wires for rear 6×9 but there are 4, witch of the other two wires are + & -, THANX FOR YOUR HELP
The aftermarket radio i installed isn’t getting any power. I connected the power wire from the radio to the orange wire from the car and the ground is connected but still no power. What could it be?
Steven, it sounds like you blew out a fuse or two. Double check ALL your fuses and you will probably find a blown fuse somewhere. Sometimes when you short out your radio fuse, other fuses may also blow out. Hope this helps. Good luck.
Thanks
Elj, we are glad we could help you with your 2004 Chevrolet Cavalier stereo wiring diagram needs.
solved problem becasuse of the wire not being hooked up to the fusebox. how do you do that??
Just like chris. iv removed all the speakers and the back 2 the 6″-9″s have 4 wires for each instead of 2. I was wondering what the other 2 thats arnt listed for each speakers would be used for and if they even need to be used
I want to hook up my ipod to my stereo, so is there a RCA port in the back of the stereo that would connect to my ipod?
Adam, most late model vehicles do not have rca outputs on the factory radio to feed an audio signal to your aftermarket amplifier. You would have to install a line out converter to supply an audio output. Here is the Line-Out Converter you need:
Scosche 2-Channel Speaker to RCA Line Out Converter
When splicing in the RCA Line Out Converter, tap your factory rear speaker wires to get a full range audio source. We suggest you invest in some solid wire taps that wont come loose. These wire tap connectors will allow you to tap into wires without cutting and installs in seconds by hand with no crimping or tools required. If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck.
i just recently installed a new stereo in my 2004 aveo and have the 2 illumination + and – wires left over. I am assuming they have something to do with the in dash lights but we are unsure where to splice them??? can anyone please help?
So Adam, Chris, and Justin, did you figure out the 4 wires to 2 wires thing? I don’t get it.
i am having the same problem as everyone it seems. i have an 04 cav ls sport and i also have four wires i need to make into two. Did anyone find the answer?
i connected the head unit and left the blue wire (remote) and tel muting wire (brown) alone and its working fine .. thanx for the diagram … peace
Sergiu, we are happy we could help you with your 2004 Chevrolet Cavalier stereo wiring diagram needs.
I have installed a new radio in my 2004 chevrolet cavalier. i am getting no power. I checked all fuses and they are not blown. HELP!!!!
Jon, first double check ALL your fuses and make sure ALL your fuses are good. You can do this by using an Automotive Fuse Tester and making sure all of your fuses are not blown. If all of your fuses are good, your 2004 Chevrolet Cavalier may have a factory amp that needs to be turned on by your after market radio. The car radio amplifier trigger wire has to be wired up to turn on your factory amplifier to output sound from your speakers. Double check that your 2004 Chevrolet Cavalier amp turn on wire is connected. Hope this helps. Good luck with your 2004 Chevrolet Cavalier stereo installation.
