What is the radio system in a car called?
It’s often called a radio, but “head unit” is a more appropriate term for this component since it is the brains and command center for a car’s audio system. It generates sound from both “over the air” signals, such as radio, and recorded formats, such as a CD and other digital media.
What is a wiring harness for car stereo?
Many wiring harnesses can let you keep your vehicle’s factory amplifier when replacing the stock radio. They include connections that directly tie the outputs of your new car stereo into the factory amplifier’s inputs. So, you’ll be using the factory power for your speakers, instead of the power from your new radio.
How can you tell which wire is positive?
If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire. Run your fingers along the wire to determine which side has the ribbing. Feel the other wire which is smooth. This is your positive wire.

Why do some cars have harnesses behind the radio?
Vehicle audio systems, electrical systems, and convenience features have come a long way. So, the harnesses had to evolve to handle the complex wiring and data information that modern cars use. In some vehicles, you need to plug in the harness somewhere other than behind the radio.
How do you fix broken wires on a car stereo?
You melt the solder onto the wires to stick them together and as the solder cools it forms a permanent bond. Twisting wires together and then covering them with heat-shrink wrap or electric tape will suffice for car stereos.
What do the symbols on a car stereo chart mean?
