  • 1Test the stereo. Before you install the stereo in the center console of your vehicle, reconnect the battery and turn the car on to make sure it is functioning properly. With the stereo completely connected, turn it on and try a few functions. Make sure all speakers in your vehicle are working and that CDs or your MP3 player play properly. If you have been able to connect the antennae cable already, check to make sure the radio works.
  • Checking the stereos functions now will prevent you from having to take the console apart again to address any issues with the wiring.
  • If something does not work properly, review the connections with the wiring diagrams that you have to make sure all of the wires are connected to their corresponding match.
  • Remove the keys and disconnect the battery again after youve tested the stereo.
  • 2Tuck all of the wiring into the dashboard. You may have noticed that most of the wires you connected to your stereo allowed for quite a bit of slack. Take the connected car stereo in one hand and use the other to tuck all of the extra wire back into the dashboard as you set the stereo in its opening. If you have not been able to connect the large antennae cable yet because it was too short, connect it now as you sit the stereo in its place.XResearch source

    How To Splice Car Audio Wires

    The first and most important factor we will have to grasp is understanding how to splice .

    This is going to be the majority of the work in building a car stereo harness. Hence we have to understand the correct and incorrect ways to splice wires.

    The preferred method of removing the insulation shield is using wire strippers because they are specifically designed only to remove the wires insulation shield and not damage the internal wiring.

    If you use scissors of any kind, you will most likely damage or remove some of the wire.

    The best method of connecting wires together is to solder them. Many people often crimp wires together using a terminal, but that method is also subject to wear and tear and can eventually lead to faults.

    Heat Shrink is by far much more effective than electrical tape and is far more robust, withstanding a lot more punishment than electrical tape can handle.

    Check out the video below, where you will see how to splice and connect car audio wire.

    Wrapping All Connected Wires To Secure Them

    Once you checked all the wires, and then connect them with the car very carefully. Its better to make the connections permanent. There should be no bare wire in your car stereo otherwise it will harm you. Wrap all the wire connections with some tape.

    There are some other ways by which you can wrap wires but with tape is the most common is the easy way of all.

    When you are connecting two wires, it requires solder or soldering wire .for that, first melt the solder, place melted solder onto the two-wire connections and wait until it cools down and sticks properly to the wire connections.

    Now it becomes a permanent bond and after that wraps the connection with some tape. Connectors are also available in the market .you just have to put both wires into it and twist them with your fingers.

    Ground The Car Wires With Electrical Tape:

    After the removing of the stereo from the car battery you should disconnect the power.

    And should ground all the wires in the car. The yellow wire should be connecting to the batter and the red wires should ground with ignition switch and black should ground at a metal ground. After removing the stereo wires in the car should need to be grounded.

    Installing A Used Car Stereo With Or Without A Pigtail

    Car Audio System Diagram Layout

    If you have a used car stereo that you want to install and the pigtail that came with the head unit, check the list above to see what each wire in the pigtail needs to connect to.

    If you don’t have the pigtail, look for an adapter that’s designed to connect that head unit to your make and model of car. If that doesn’t work, obtain a replacement pigtail to proceed anyway. Hopefully, the colors of those wires will match up to the aftermarket standard.

    Otherwise, you’ll need a wiring diagram, which is sometimes printed on the exterior of the head unit or available online.

    Something To Go By For Factory Wiring

    All vehicle manufacturers use a different color code for their wiring so there is no universal color code I can give you for every vehicle. There are, however, resources available to get these color codes. I like to use the12volt.com to get factory wiring information.

    Now, I know it would be tempting to just start matching up wire colors and get the harness connected but it is always a good idea to verify all the wires before making your connections. Ive seen resources give the wrong information before so its just a good habit to get into.

    Get Started On The Wiring

    Don’t screw the new stereo into the bracket just yet. It’s time to start the wiring process. Since you were smart and purchased the wiring adapter with your car stereo, all you have to do is connect the new stereo’s wiring harness to the adapter, and it’s plug-and-play.

    To connect the stereo’s harness to your adapter, you’ll need to strip the wires and crimp the connections. Never install a new car stereo using only electrical tape or those twist-on type connectors used in house wiring. These aren’t acceptable or safe ways to keep automotive wiring in place.

    Matthew Wright, author

    Many car stereo wiring harnesses will have a screw type connector at the end of the ground wire. If for some reason your current stereo was not grounded through a wire you can ground the car stereo by finding a screw under there to which this wire can be attached. If your car is like most and has a ground wire for the car stereo already, just cut the connector off and crimp it to the adapter harness.

    Matthew Wright, author

    Once you have all of your electrical connections made, plug the adapter into the car’s wiring harness. Then plug the stereo itself in for a test run. It may seem silly, but the worst time to find out about a wiring issue is after you have re-installed all of those trim panels! Once you’ve checked the power and all of your speakers, unplug the stereo unit.

    Wiring is finished the car stereo works. Now all you need to do is put the new stereo into the bracket. It should have holes in the side just like your old unit did. Use the screws that came with the new car stereo they will be correctly sized. Once it’s in, snap the trim plate onto the outside.

    How To Test A Car Radio

    What to do and not When Installing (Car Stereo Wiring)

    To test a car radio, there are 3 main things youll need to do:

  • Connect the power and ground wiring
  • Use a test speaker on the speaker outputs to verify they work
  • Try out any other audio functions youll need to use
  • 1. Connecting power to the radio

    As I mentioned earlier, you can use a +12V to 13.8V DC power supply for your car radio. Optionally, if you dont have a 12V supply you can temporarily connect it to a 12V car battery long enough to check out the radio.

    In either case, youll need to do the following:

  • Connect the +12V BATT and ACC wires together then to the +12V source. Youll need both wires to be connected for the radio to turn on. Connect both of these to the +12V output of your supply or the battery.
  • Connect the ground wire to the negative supply or battery terminal.
  • Be sure to insulate any unused exposed wires including the speaker wires . You dont want any wires shorting together during testing. For insulating them, electrical tape works great or you can use duct tape or even masking tape carefully if you must. Id avoid transparent Scotch tape as it tends to come off too easily.

    The idea for testing is to temporarily do what you need to for checking that it works. For a real vehicle installation, better connections like crimp connectors should be used.

    CAUTION:If using a vehicle battery to power you radio under test, never allow the metal case of the radio near the battery.

    2. Testing the speaker outputs

    To test the speaker outputs:

    How To Install A Car Stereo Without A Wiring Harness Adapter

    Learning how to install a car stereo without a wiring harness adapter is very strait forward if you have the proper tools handy for the job! Your main goal is to install a new stereo into your vehicle while not damaging important wires or causing any automotive fires in the process.

    Ive decided to create a step by step guide for this, it will be pretty quick and easy to understand hopefully. Ill list the tools that I recommend having handy for this job below as well.

    What Gauge Wire Is Used For Car Stereo Harness

    Wire gauge, by its typical definition, is the measurement of a wires diameter. The size of the diameter will determine the amount of current that the wire can safely carry. The wire gauge will also determine the electrical resistance of the wire itself .

    Typically the car stereo will have wires with a wire gauge between 14awg and 18awg.

    The power lead will have the thickest gauge , and the rest of the harness wire will be thinner, typically between 16awg and 18awg.

    How To Install The New Stereo

  • 1Match up the wires. Match the wires of the cars harnesses to the new stereos harnesses. Each harness connector is unique, so it should be easy to figure out which ones fit together.
  • To be safe, check the wiring diagrams for both your car and the new stereo to verify youve connected them correctly.
  • If your car’s stereo doesnt use wire harnesses, youll need to match up each wire manually. The wires are color-coded however, the wires on an after-market stereo may not match with the color-coded wires in your vehicle. It’s best to study and follow the wiring diagram that came with the stereo.
  • Connect the matched wires. There are two options for connecting the wires, crimping or soldering. Crimping is faster and easier, but soldering will provide a more stable and secure connection. Be sure to use the proper size crimper and dont try to bundle the wires with tape it will eventually dry out and fall off. Bundle wires using zip ties instead.XResearch source
  • 2Assemble the mounting kit. If your new stereo came with a separate mounting kit, assemble it according to the stereo’s instructions .
  • Push down on the tabs located around the metal sleeve with a screwdriver to secure the metal sleeve in place.
  • 3Connect the power source. Typically, if you have a wiring harness, this connection will be made when you connect the new stereo harnesses to the harnesses in the car.
  • Check For The 12v Wire

    Set your multimeter to the appropriate scale, connect the ground lead to a known good ground, and touch the other lead to each wire in the speaker wire. When you find one that shows approximately 12V, you have found the constant 12V wire, also known as the memory wire. It’s yellow in most aftermarket head units.
