Car stereo help

I installed a Sony aftermarket stereo into my '99 saturn car recently. I usually just hook up the red, yellow, and ground wires first to make sure northing is wrong. When i do, the unit makes an ejecting noise, but the front display does not turn on. I checked fuses, wiring, everything is hooked up right. Could it be that a different size fuze is needed, or that a different wire, other than the yellow, red, and ground is needed for the display to turn on?

There are some tests you can perform for checking the stereo. Yes, you are right, there is a yellow and red wire. Yellow constant power, red is switched throught the ignition. During the installation, you may have blown a fuse. A bigger fuse is not needed, stick with the same size if you find a bad fuse. Hook the red and yellow wire together for TESTING PURPOSES to one or the other of the hot wires in the vehicle. This will also test to see if you have a bad fuse. If the stereo powers up in one or the other power connections in the car and works, you have a blown fuse. I have seen some fuses be located under the hood of the car near the car battery. Hope this helps, Bob

Why wont my personal setting save for my Kenwood KDC-X493 car CD reciever? This is my 2nd aftermarket cd reciever and just like the 1st one I'm still having this problem.


Make sure you have the +12VDC and the Ignition leads hooked up properly.

If your head unit is pulling is power off of the IGN lead, it will reset every time you turn your car off.

I am trying to hook up a new car stereo in my 1992 honda civic, when i hook it up nothing comes on but i know there is power cause if i hook an old radio up it works please help


Hi and welcome to FixYa,

Initially on most aftermarket car stereos, confirm that the following wires are connected as described:
  • yellow - to an always available +12 such as the battery's + terminal;
  • red - to an switched +12 such as the ACC terminal of the ignition switch; and
  • black - ground preferably to a metal frame support/bracket rather than the harness ground.
Good luck and thank you for asking FixYa.

Not for sure which is the hot and which is the ground wire.


Solid black is always ground on aftermarket head units. Red is usually the ignition wire, ie when you turn your car on, your stereo turns on. Hot or positive is usually yellow and usually the biggest wire

CDX-RA700 will not get power from my Honda Civic


Automobiles use Direct Current "DC" and is very dependant on a good ground. The black wire from your stereo should be the ground and needs to be attached to the chassis "metal part of the car". You can use an ohm meter to check for grounds by placing one lead on your door hinge (unpainted) and the other to where you are connecting your ground from the stereo. Be sure that this wire does not have voltage on it with the key off, on acc, or in the on position or you could blow a fuse or damage your equipment. Besides that make sure that you have 12v constant to the (usually red wire) and switched (voltage only with the key on) to (usually the yellow wire). Hope that helps. It's mostly about the ground.

Stero not coming on


What kind of car do you have? This can make the difference. Many cars with small engines (eg. Geo Metro) simply do not generate enough power to operate the radio. Other times the car can generate enough power to support the radio, but when you plug something into the cigarette lighter/power outlet the radio shuts off because the car isn't powerful enough to handle both. The first thing you need to do is to make sure that the car's electrical output is sufficient to operate the radio, after that it would be a good idea to make sure that all of the wires are connected properly.

Aftermarket stereo install


Was it working before?

I would hate to have you crack it open when maybe the ground wires arent hooked up right. Unless you have a scope go online and get the manual on wiring it to ensure you did it right.
