Newly Installed Car CD Player won't power up

I installed a new cd player for my car by myself, but it won't power on. The only thing that seems to work is a little flashing red anti-theft light. Does this indicate that the wiring is ok? I checked all the connections to make sure they were tight and that each wire was connected to the right one and all looked good. I also changed the fuses in the fuse box, but that didn't seem to make any difference either. I'm getting pretty frustrated, because I really don't know what else to do! Please help! Thanks so much!

Re: Newly Installed Car CD Player won't power up

When you see this problem, it usually means you have power on your deck's constant power wire (usually yellow) but no power on the accessory power wire (usually red). The accessory power wire is the one that sends voltage to the deck when the key is turned on. Usually this means that the red wire is either connected to the wrong vehicle wire, or that the vehicle's radio fuse is blown. As a last resort, you can disconnect the red wire from whatever it's connected to, and re-attach it to the same connection as your yellow wire. This should allow the radio to power up, but it won't turn on and off with the key-switch; you'd have to remember to turn it off or remove the face when you leave the vehicle, or you may drain the battery. Alternately, you can extend the red wire to a different source of key-switched voltage. Depending on the vehicle, you may be able to find this behind the cigarette lighter, at the key switch itself, or at the fuse box.

SOURCE: No Power

make sure you have power at the end of the harness which connects to the deck. also insure that you have the 12v constant and 12v interupited hooked up correctly. this is usually the problem when the deck reconizes power but not to power it. also make sure you have the key on acc.  becasue this is one way to connect the 12v interupted.

Cant get no sound

Try a different input source. I have had this happen before and the easiest way to diagnose the root of the problem was to take a home CD player out to my car and use the outputs to power the amp. If the amp works, move upstream to the RCA wires (unplug them from the back of your head unit and plug them into the home CD player). If that works, you know the stereo isn't putting out a signal. Good luck!!

Hello pinkperry,

It sounds like the wiring between the cdplayer and the dash has come loose. When the wires are not making proper connections some of the speakers or functions of the radio cut on and off.

This is just my first thought and the easiest thing to fix. You will have to remove the cd player from the dash. After which you will want to check the wiring. Chances are your cd player has a harness if it's an aftermarket cd player installed in your car. If it does there will be two sets of wires to double check.

Just make sure all the wires are securely twisted together (the sets of wires) and taped up with electrical tape.

Try that and post back if you have any further questions. Thank you for choosing Fixya!

No Power

Make sure u have power at the back of the radio. U said u replaced the fuses in the fuse box. Some aftermarket units have in-line fuses that can be open. So, check to see if there is an in-line fuse for the memory/back-up and B+ leads. If there is, more than likely, one of them is blown.

My amp only powers the subwoofer when the radio is on but wont when the cd player is on

The person(s) who hooked up your system made a boo boo. They wired your remote turn on lead to the power antenna lead instead of the amp turn on line (both are blue and easy to mix up). Thus when your radio is on it sends a signal to the amp and the amp turns on, but when you set to CD the signal goes away and your amp shuts down. Easy fix, just re-wire the amp turn on lead and the problem will be fixed.

You're using the wrong control wire. You're likely using a wire marked antenna control. You need to use the one marked amp control. They are both blue.
