What Color Wires Go Together In A Car Stereo?
When installing a car stereo, it is important to connect the wires with the correct polarity. The best way to do this is to use a wire harness that is specific to your car. This will ensure that all of the wires are connected in the correct order. If you are unsure which wire goes where, consult your car’s owner’s manual or a professional installer.
It is also important to use the proper size wire for your application. For most applications, 16 gauge wire will be sufficient. However, if you are running long lengths of wire or connecting multiple amplifiers, you may need to use a thicker gauge wire. Consult your car stereo’s owner’s manual for specific recommendations.
Finally, make sure to use quality wire connectors to ensure a secure connection. Solder connections are always the best, but Crimp Caps or Wire Taps can also be used. Avoid using bare wire or electrical tape, as these are not reliable methods of making a connection.
How To Install an Aftermarket Stereo Without Harness
1. Remove the factory stereo. This will require a few different tools, including a screwdriver and possibly some panel removal tools.
2. Once the factory stereo is removed, you will need to remove the mounting brackets that held it in place. These are usually attached with screws or bolts.
3. With the brackets removed, you should be able to see the wiring harness that is connected to the stereo.
4. Using a wire stripper, remove the plastic cover from the end of the wire harness. Be careful not to damage any of the wires.
5. Next, you will need to identify which wires are responsible for powering the stereo and which are responsible for the speakers. In most cases, the power wires will be a different color than the speaker wires.
6. Using a wire cutter, cut the power wires and the speaker wires. Make sure to leave enough wire so that you can connect the new stereo.
7. Strip the ends of the wires using a wire stripper.
8. Connect the wires to the corresponding terminals on the new stereo. In most cases, the power wires will be connected to the red terminal and the speaker wires will be connected to the black terminals.
9. Secure the new stereo in place using the mounting brackets.
10. Test the stereo to make sure it is working properly.
