Car Stereo Wiring 101 – A Must Read!
I have many car radio in the last 10 years or so to come. There are so many "techniques" for the installation of head units. Everyone has their own opinion about what is right and wrong when wiring a system, but because it simply does not make it right.
I asked Majestic changes, what was their opinion on the subject. How do they come to install as many units, and always right?
Firstly, if applicable, always use the seatbelts. The aftermarket wiringDish is usually taken from the guesses of the plant. These straps attach to the vehicle's factory wiring harness and gives you a color-coded installation. They measure only know red, red, yellow to yellow, etc. But is that all an installer should do?
Starting with your digital multimeter, in the search for energy sources in the harness. A source is 12 volts continuously, the other is the ACC (ignition) 12 volts. These two go with the yellow and red wires from theAftermarket head unit to use. They are labeled accordingly. It's usually a good idea to attach the grounding wire to the frame of the dashboard. A lot of head units are equipped with a connector already attached to the grounding cable. Secure it in place with some solder and heat shrink tubing. Be connected Slide the shrink tubing over one of the lines and move them out of their way. Connect the cables and dab a little solder onto the wires. Allow to cool and then slide the heat shrink tubing over theConnection. Heat with a heat gun / hair dryer to shrink to fit the tube.
You can try to look on the Internet for the wiring colors, but good luck. They will tell you the "typical" wire colors, but chances are it will be different. You can try two methods to find the right wires. Clip the rest of the wires to use from the factory. You can test the speakers with a good 9-volt battery, which speakers can be seen, the. Two wires of the same speakers connected to it will pop. Notewhereby the speaker pop and add the fact that the speaker wiring from the ECU. I like turning the unit on and make sure that the wires are the correct polarity. A reverse wired speakers will not sound as good as a properly grounded book. Put the technique until all the speakers are connected.
The other way you can turn the speakers down on the head trace device, but be very careful not to be crossed any wires. Start with a pair of wires, and add them one at a time until youTo receive sound. She, who is speaker wire and attach it, note the speaker of the wiring, not the polarity. Continue until all lines are available. Cable tie the cable neatly and put them behind the head unit.
Make sure you have a good ground wire connection. Make sure to run RCA jacks or signal lines, away from any power wires or springs and are not parallel to them.
If you want a nice trick, you can add the 12-volt under-the lighting wireand you can use the device with the parking light switch off. Note that at any time the device, the dashboard lights are on, but you will not notice it in the day. The illumination wire is used to make the factory radio lights in the night.
Not with the wiring for your car is not done or the situation. If you get the belts, you're saving the expense and time and use. If you are in a quandary, then follow the steps above and get itcorrectly installed.
