If you’re a proud owner of a Dodge Avenger, you may want to upgrade your car’s audio system. To do that, you need to know the wiring diagram of your car’s radio. In this article, we’ll provide you with a comprehensive 2011 Dodge Avenger radio wiring diagram that you can use as a reference for your installation. Let’s get started!
The Wiring Harness
The wiring harness is the collection of wires that connect the radio to the car’s electrical system. In some cases, the wiring harness may come with the new radio you’re installing. However, if you’re installing an aftermarket radio, you may need to purchase a wiring harness separately.
The wiring harness consists of several wires with different colors that correspond to different functions. Here’s a breakdown of the most common wire colors:
| Wire Color | Function |
|---|---|
| Yellow | Battery positive |
| Red | Ignition/Accessory positive |
| Black | Ground |
| Blue | Power antenna/Amplifier remote |
| Orange | Illumination/dimmer |
What is the Yellow Wire for?
The yellow wire is for battery positive. This wire connects to the car’s battery to provide constant power to the radio. Even when the car is turned off, the radio will still have power. This allows the radio to save station presets and other settings.
What is the Red Wire for?
The red wire is for ignition/accessory positive. This wire connects to a power source that only has power when the ignition is turned on or the key is in the accessory position. When the key is turned off, the power to the radio is shut off.
What is the Black Wire for?
The black wire is for ground. This wire connects to a metal part of the car’s chassis to provide a ground connection for the radio. A solid ground connection is important for the proper functioning of the radio and to prevent electrical noise.
What is the Blue Wire for?
The blue wire is for power antenna or amplifier remote. If you have a power antenna or an external amplifier, you’ll need to connect this wire to the appropriate accessory wire on the car’s radio harness.
What is the Orange Wire for?
The orange wire is for illumination/dimmer. This wire connects to the car’s light switch and allows the radio to automatically dim when the headlights are turned on. If your car doesn’t have an illumination/dimmer wire, you can usually leave this wire disconnected.
Speaker Wires
The speaker wires are the wires that connect the radio to the car’s speakers. The wiring diagram will show you which wire goes to which speaker. The most common wire colors for speaker wires are:
| Wire Color | Function |
|---|---|
| White | Left front speaker (+) |
| White with black stripe | Left front speaker (-) |
| Gray | Right front speaker (+) |
| Gray with black stripe | Right front speaker (-) |
| Green | Left rear speaker (+) |
| Green with black stripe | Left rear speaker (-) |
| Purple | Right rear speaker (+) |
| Purple with black stripe | Right rear speaker (-) |
How do I identify the Positive and Negative Speaker Wires?
The positive speaker wire is usually marked with a (+) symbol or a solid stripe, while the negative speaker wire is usually marked with a (-) symbol or a dashed stripe. If you’re not sure which wire is positive or negative, you can use a 9-volt battery to test them. Touch the positive wire to the positive terminal of the battery and the negative wire to the negative terminal. If you hear a slight pop or thump, you’ve identified the correct wires.
Conclusion
By following the wiring diagram and understanding the function of each wire, you can easily install a new radio in your 2011 Dodge Avenger. Remember to always use proper wiring techniques and to double-check your connections before powering on the radio. Happy listening!
