If you are looking to upgrade the audio system in your car, you may need to install an aftermarket amplifier. In most cases, this requires a line output converter to convert the speaker level signal to a preamp signal that the amplifier can use. This article will provide you with a step-by-step guide on how to wire a Metra output converter.
What is a Metra Output Converter?
A Metra output converter is a device that allows you to convert a speaker level signal to a preamp signal. It is used to install an aftermarket amplifier in a car audio system that has a factory radio. The Metra output converter is a preferred option because it is easy to install and provides high-quality sound.
Why Install a Metra Output Converter?
The main reason for installing a Metra output converter is to ensure that the aftermarket amplifier is compatible with the factory radio. Without the output converter, there will be a mismatch in the signal levels, which can lead to distortion and poor sound quality. By installing a Metra output converter, you can ensure that the amplifier receives a clean and clear signal that is compatible with the factory radio.
What You Need
Before you start wiring the Metra output converter, you will need the following:
- Metra output converter
- Wire strippers
- Crimping tool
- Wire connectors
- Tape
Wiring the Metra Output Converter
Follow the steps below to wire the Metra output converter:
Step 1: Remove the Radio
To access the wiring behind the factory radio, you need to remove the radio from the dashboard. The process of removing the radio varies depending on the make and model of the vehicle. Consult the manual for your vehicle to find out how to remove the radio.
Step 2: Identify the Wiring
Once you have removed the radio, locate the wiring harness that connects to the back of the radio. The wiring harness will have several wires, including the speaker wires.
Step 3: Strip the Wires
Use a wire stripper to strip the insulation off the speaker wires. You will need to strip the wires that correspond to the front and rear speakers. Make sure you strip enough insulation to expose the wire without cutting it.
Step 4: Connect the Metra Output Converter
Connect the speaker wires to the Metra output converter. The output converter will have two sets of wires: input and output. Connect the speaker wires to the input wires on the output converter. Make sure you match the positive and negative wires correctly.
Step 5: Connect the Amplifier
Connect the output wires from the Metra output converter to the input wires on the aftermarket amplifier. Again, make sure you match the positive and negative wires correctly.
Step 6: Power the Amplifier
The aftermarket amplifier will need power to function. Connect the power wire from the amplifier to the car’s battery. You will also need to connect the ground wire from the amplifier to a metal surface in the car.
Step 7: Tidy Up the Wiring
Once you have connected all the wires, use wire connectors to secure the connections. Use tape to wrap the wires and prevent them from coming loose. Make sure you tidy up the wiring and replace the radio in the dashboard.
