Battery Power (Red Wire)
The red wire is the battery power wire, which provides a constant supply of power to the radio even when the ignition switch is turned off. This wire connects to the positive terminal of the car’s battery.
It is important to ensure that the red wire is properly connected and fused to avoid any electrical damage to your car.
Ignition Power (Yellow Wire)
The yellow wire is the ignition power wire, which provides power to the radio when the ignition switch is in the “on” position. This wire connects to the ignition switch.
Make sure to connect the yellow wire to the correct source to avoid any issues with the radio turning on or off when the ignition switch is turned on or off.
Ground (Black Wire)
The black wire is the ground wire, which completes the electrical circuit and provides a return path for the electrical current. This wire needs to be properly grounded to ensure the radio functions correctly.
Make sure to connect the black wire to a suitable ground point on the car’s chassis, such as a metal bolt or screw.
Speaker Wires
The speaker wires are color-coded according to the polarity of the speaker. The gray and white wires are for the front speakers, and the green and violet wires are for the rear speakers.
The wires with stripes (gray/black, white/black, green/black, and violet/black) are the negative speaker wires. The wires without stripes (gray, white, green, and violet) are the positive speaker wires.
