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.

With the radio on, make sure there is voltage at the speaker wire positive and negative leads. If there is no voltage, the output from your receiver might have gone out.

Radio sound low and squeeky, works good in summertime


The volume control on your radio is called a potentiometer, which may be going bad. It works better when its warm because materials expand as they warm up and make tighter contact with each other.

It is also a possible a bad wiring connection exists. Poor contact will cause static, poor audio quality and intermittent output.

Your radio will have plug type connector(s) Your speakers will most likely each have two wires with single female spade connectors of different widths (keeps the polarity correct) the wire with the stripe (of whatever color) will be connected to the negative (-) speaker terminal.

So you need to check all the connections, one is making poor contact.
If both speakers (assuming you have two) sound good or bad... then start with the plug connectors for the radio and any independent black ground wire coming out of the radio.

If one speakers sounds okay check the connections on the other one. You check the connections by carefully pulling the speaker wire off of the speaker and then carefully pushing it back on making sure it feels tight and secure.

PS: If you pull the fuse for the radio, the radio will have no power and will not work. The radio coming on proves the fuse is good.

PSS: Your owners manual should provide lots of information on your sound system components.

There is no sound coming from the speakers, not even the bluetooth. The volume control on the steering wheel and the knob also doesn't work. The radio, cd & dvd player work fine.


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.

I've installed an after marker cd player and my digital display doesn't show on my climate control. How do I fix this?


You may have a bad control or while you where in the dash installing the cd player you may have cut into a wrong wire or pull a connector out a little causing it not to connect good, you will need to go back inside and check the wiring to the controls and check the wires you may have used to connect the player also make sure you didnt pop any fuses by mistake by wiring something wrong, the most common reason for a problem like this is due to connecting the light wire from the stock radio to the wrong wire, this wire is connect to lights for night driving, it lights up old radio at night for the display and i think this is your problem and may have blown the fuse, so if this is the case you will need to replace the fuse and locate that wire and disconnect it and tape it as its not used in the aftermarket radios.good luck and have a good day.

Best Buy installed a new cd player in my 03 Tiburon GT. All of my instrument cluster lights no longer work. The fuse is ok. Anyone know the wiring color codes. Best Buy is unco-operative and want me to...


Is fuse 29 the one you say is good? If that fuse is good, check your tail lights. If the tail lights are not working either, check the TAIL LAMP fuse in the engine compartment relay box.
There are 2 different wiring diagrams depending on if you have the amplifier or not. If you have only the basic radio, it would not have the amp. If you have a premium option, it would have the amp.
There is also another wiring color code I got from another website that's different--more like the standard colors. I'm going to include that color code as well in case you find the colors don't match the diagrams.
In the diagrams, there are actually 2 wires that run the light on the radio. One is green and one is brown with a white stripe. An aftermarket CD player will probably not have any wires for the light and just have it come on when the radio is on--day or night. So, if they connected those factory wires anywhere, that may be your problem.
I have pasted all of the relevant wiring diagrams below, though they may be hard to read because of picture size policies at FixYa. Please let me know if you have more questions.
