Chevy Cobalt - How to add an amp to boost the factory subwoofer

Introduction

This tutorial will guide you through the process of adding an amplifier to boost the factory subwoofer in your Chevy Cobalt. This setup provides an affordable way to enhance your audio experience without the need for extensive modifications or expensive equipment. Whether you have the factory Pioneer system or not, you can still achieve better bass performance.

Step 1: Gather Your Materials

Before starting, ensure you have all the necessary components:

• Amplifier
• Subwoofer (optional, depending on your setup)
• Subwoofer enclosure (if using a separate subwoofer)
• Line-out converter (LOC)
• Speaker wire
• RCA cables
• Power wire with fuse
• Ground wire
• Remote turn-on wire
• Basic tools (screwdriver, wire stripper, etc.)

Practical Tip

Choose an amplifier that matches the power rating of your subwoofer to avoid damage and ensure optimal performance.

Step 2: Access the Factory Subwoofer

• Open the trunk of your Chevy Cobalt.
• Remove any necessary panels to access the factory subwoofer wiring. This may involve unscrewing or unclipping some panels.
• Locate the wires going to the factory subwoofer. These will typically be identified by their colors.

Step 3: Connect the Line-Out Converter

• Connect the line-out converter to the wires leading to the factory subwoofer:
  • Identify the positive and negative wires for both the left and right channels.
  • Connect these wires to the corresponding inputs on the LOC.
• If you don't have the factory subwoofer, you can access the left and right rear speaker wires in the trunk instead.

Common Pitfall

Make sure the connections are secure to prevent any audio loss or distortion.

Step 4: Connect the Amplifier

• Using RCA cables, connect the output of the line-out converter to the input of the amplifier.
• Connect the power wire from the amplifier to the car battery, ensuring you include a fuse close to the battery to protect your system.
• Attach the ground wire to a clean, unpainted metal surface in the trunk.

Step 5: Connect the Subwoofer

• If using a separate subwoofer, connect it to the amplifier according to the manufacturer's specifications.
• If you are using the factory subwoofer, ensure it is properly connected to the amplifier.

Step 6: Find a Remote Turn-On Wire

• Identify a suitable remote turn-on wire in your vehicle. This is typically found in the ignition harness or the factory radio harness.
• Connect this wire to the amplifier's remote input to ensure it powers on when the vehicle is started.

Step 7: Test the Setup

• Before securing everything back in place, test the audio system.
• Turn on your vehicle and check that the amplifier powers on and the subwoofer produces sound.
• Adjust the settings on the amplifier for your desired bass level.

Conclusion

By following these steps, you can successfully add an amplifier to boost your Chevy Cobalt's factory subwoofer, enhancing your audio experience without breaking the bank.
