Cqdf903u powering on but no sound in 2001 vw jetta
I am getting power but no sound all wires are hooked up in the dash and the wiring harness. very irritated that im getting no sound whatsoever. it is the stock speakers. the only thing i can come up with is that i might have the wrong wiring harness for the 8 speaker system. It allows me to plug in the front and rear speakers into the harness but not the front and back tweeters in the doors. but i would still get sound wouldn't i

no you cant just hook it to a red wire because its red. what are you hooking up? im assumeing a stero, you can however hook up it without a "harness" but you need to know what you are hooking up. since its red its most likely a power wire on your stero but not always the case on the vehicle. also some wires are switched power or "remote" power meaning when the key is turned off they are not electricfied or "hot" and some are constant meaning they ar always hot. give more details and i can help more.
unless you have a power antenna or an external amp, all those are extra wires. just cap them off. the orange wire is only used if the radio has an illumination feature that allows dimming on the radio. it is not needed to see the radio. DO NOT connect the blue/white from the radio to the orange of the harness. whenever you turn the radio on it will send 12V to your cars illumination circuit. this could damage your lights, dash lights and maybe the radios output.
There is a good chance that your model of vehicle has its own amplifier and if it does then it will have to be by-passed. As i am not very familiar with American vehicles i can't tell you exactly which harness or adapter you need to purchase. As for the unit staying on without the Ignition on: Switch over the red wire with the yellow wire and the yellow with the red. That should solve it.
The 2 blue wires are: solid blue for power antenna and blue with stripe for remote turn on for external amplifier. The Pink is cellular phone mute.
if your car doen't have a factory harness that you can grab power (+) and ground (-). you can run one wire from the battery (fused 10-15amp) and connect that to the yellow wire on the sony. Then find a fuse in your glove box (preferably the cigarette lighter fuse) that send power when the key turns to ignition (fuse that also) then hook that wire up to the red wire coming out of the sony. As for the black wire coming out the back, find the closest bare metal behind your dash and use a self-tapping screw to secure the wire to that. If you do have a harness behind your dash you can normally get all those wire in that harness (saves a lot of time).
Sounds like you have the ground for the radio hooked up to the illumination ground wire. Check for orange or orange/black wire coming from the radio harness. Did you buy the harness for the car as well? If so then just match all the colors of wires from the car harness and the radio harness. By car harness I mean the harness that plugs into the harness that the original factory radio plugged in to.
hello chevi1981..what can happen is if whoever installed your system did not run your speaker wires properly eg if they have worn through and touching metal or a screw through the wires ,it can blow the audio ics in unit resulting in no sound.all these high powered units have above ground circuits in the audio stage .to check ,hook up a separate speaker direct to your unit,separate wiring ,if no sound, will most likely be the intergrated circuits..these will have to be changed by a tech as cd players are a beast to work on,also your 2 speaker wires should not touch one another.with your sec code if your have a removable face you may not have a code ,as removing face is your security .hope this helps
make sure none of the speaker+/- wires are contacting each other. if even one of them does, most likely all the sound will cut out to protect the internal amplifier. Other than that, the blue/white remote wire is most likely your problem, if the car has some sort of factory amp thats the wire that tells it to turn on and let sound through. its possible that the outputs of the deck are bad, try checking it with a test speaker or in another car
