The 2016 Nissan Altima comes with a standard radio receiver that can be upgraded to other models with added features. In this article, we will look at the wiring diagram for the 2016 Nissan Altima radio, giving you a better understanding of the wiring system and how it works.
Understanding the Nissan Altima Radio Wiring Diagram
The Nissan Altima radio wiring system is made up of several components that work together to produce a clear sound. These components include the power supply, speakers, amps, and radio unit. The wiring diagram explains how all these components are connected, creating a circuit that powers the sound system.
The diagram consists of several lines, symbols, and colors, representing different components and connections. The colors do not always correspond to specific wires or pins, but rather indicate the function of the wire. Here are some of the colors and their meanings:
| Color | Meaning |
|---|---|
| Red | Power |
| Black | Ground |
| Green | Front/left speaker |
| Purple | Rear/right speaker |
| Blue | Amp/antenna |
The diagram also shows the pin numbers, wire gauge, and other information needed to understand the connections.
Power Supply Wiring
The power supply wiring provides the necessary voltage to the radio system, allowing it to operate. The red wire is usually the power wire, while the black wire is ground. It is important to make sure that the power supply wires are correctly connected to avoid any electrical short circuits that may damage the system.
The diagram shows that the red wire (pin 12) is connected to the ACC (accessory) pin of the radio unit. The black wire (pin 13) is connected to the ground pin of the system. The power supply wiring is shown in the diagram below:
Speaker Wiring
The speaker wiring connects the speakers to the radio system, allowing for the production of sound. The Nissan Altima radio system has four speakers: two in the front and two in the rear. The front speakers are usually connected to the green and green/black wires, while the rear speakers are connected to the purple and purple/black wires.
The diagram shows that the green wire (pin 2) and green/black wire (pin 3) are connected to the front/left speaker, while the purple wire (pin 7) and purple/black wire (pin 8) are connected to the rear/right speaker. The speaker wiring is shown in the diagram below:
Amp Wiring
The amp wiring connects the radio system to the amplifier, which amplifies the audio signal for better sound quality. The blue wire (pin 15) is usually the amp/antenna wire, while the yellow wire (pin 14) is for the remote turn-on signal.
The diagram shows that the blue wire (pin 15) is connected to the amp/antenna pin of the radio unit. The yellow wire (pin 14) is connected to the remote turn-on pin of the amplifier. The amp wiring is shown in the diagram below:
