Whether you’re replacing your old radio or installing a new one in your 2000 Oldsmobile Alero, you’ll need to know the correct wiring before you start. Wiring your radio incorrectly can cause problems with your car’s electrical system, and even risk damaging your new radio. In this article, we’ll provide you with a comprehensive guide to the 2000 Oldsmobile Alero radio wiring diagram, including tables and frequently asked questions.
Oldsmobile Alero Radio Wiring Diagram – Overview
Before we dive into the details, let’s take a look at the big picture of the Oldsmobile Alero radio wiring diagram. The 2000 Oldsmobile Alero has three different radio systems, each with a different wiring diagram. In this article, we’ll focus on the most common radio system, which has eight speakers and an external amplifier.The wiring diagram for this radio system can be divided into two parts: the speaker wiring and the power wiring. The speaker wiring connects each of the eight speakers to the amplifier and radio, while the power wiring connects the radio and amplifier to the car’s electrical system.
Speaker Wiring Diagram
Let’s start with the speaker wiring diagram. The 2000 Oldsmobile Alero has eight speakers, including two tweeters, two front door speakers, two rear door speakers, and two rear shelf speakers. Each of these speakers has its own wiring, which must be correctly connected to the amplifier and radio.We’ve summarized the speaker wiring diagram in the following table:
| Speaker | Circuit | Wire Color | Connector |
|---|---|---|---|
| Tweeter (LH) | A | Dark Green | C2 Pin 13 |
| Tweeter (RH) | B | Dark Blue | C2 Pin 14 |
| Front Door Speaker (LH) | C | Brown | C2 Pin 12 |
| Front Door Speaker (RH) | D | Yellow | C2 Pin 11 |
| Rear Door Speaker (LH) | E | Dark Blue | C2 Pin 6 |
| Rear Door Speaker (RH) | F | Light Green | C2 Pin 5 |
| Rear Shelf Speaker (LH) | G | Dark Green/White | C2 Pin 7 |
| Rear Shelf Speaker (RH) | H | Orange/Black | C2 Pin 8 |
Note that each speaker circuit is identified by a letter (A-H). These correspond to the circuit letters on the amplifier and radio connectors.
Power Wiring Diagram
Now let’s move on to the power wiring diagram. The power wiring connects the radio and amplifier to the car’s electrical system, including the battery, ignition switch, and ground. Incorrectly wiring the power can cause damage to your radio or car, and even pose a safety risk.We’ve summarized the power wiring diagram in the following table:
| Circuit | Wire Color | Connector |
|---|---|---|
| Battery Positive (+) | Orange | C1 Pin 11 |
| Ignition Switched (+) | Yellow | C1 Pin 10 |
| Ground (-) | Black/White | C1 Pin 9 |
| Amplifier Trigger (+) | Dark Green/White | C1 Pin 12 |
Note that the battery positive (+) wire is connected directly to the car’s battery, while the ignition switched (+) wire is connected to the car’s ignition switch. The ground wire (-) is connected to a grounding point in the car, which should be clean and free of rust and paint. The amplifier trigger (+) wire is used to turn on the external amplifier when the radio is turned on.
FAQ – Frequently Asked Questions
Now that we’ve provided you with the Oldsmobile Alero radio wiring diagram, let’s answer some frequently asked questions about installing a new radio in your car.
1. Can I install any radio in my 2000 Oldsmobile Alero?
Not all radios are compatible with the Oldsmobile Alero’s wiring, so it’s important to check the manufacturer’s specifications before you buy. Look for radios that are specifically designed for the Oldsmobile Alero, or that have compatible wiring diagrams.
2. How do I remove the old radio from my 2000 Oldsmobile Alero?
To remove the old radio, you’ll need to use a radio removal tool, which can be purchased at most auto parts stores. Insert the tools into the four holes on the sides of the radio, and then gently pull the radio out of the dashboard.
3. How do I connect my new radio to the Oldsmobile Alero’s wiring?
First, connect the power wires (battery positive, ignition switched, ground, and amplifier trigger) to the corresponding wires on your new radio’s wiring harness. Then, connect the speaker wires from the amplifier and radio to the corresponding wires on your new radio’s wiring harness. Finally, plug the wiring harness into your new radio, and then slide the radio back into the dashboard.
4. How do I test my new radio?
Once you’ve connected your new radio to the Oldsmobile Alero’s wiring, turn on the car’s ignition switch and then turn on the radio. If you hear sound from all speakers, and the radio functions correctly, then your installation was successful.
5. What should I do if something goes wrong during the installation?
If something goes wrong during the installation, stop and consult the manufacturer’s instructions or a professional installer. Don’t risk damaging your car’s electrical system or your new radio.
