Verify that all items are present:
- Scosche ES004 Noise Filter
- Two mounting screws
Setup and Installation
The Scosche ES004 noise filter is designed to be installed inline with the power supply of the audio component experiencing noise.
- Identify the Noise Source: Determine which component (e.g., head unit, amplifier) is receiving electrical noise. The filter should be installed on the power line feeding this component.
- Disconnect Power: Before beginning installation, disconnect the negative terminal of your vehicle's battery to prevent electrical shorts.
- Locate Power Wire: Identify the 12V positive power wire (+12V) and the ground wire (GND) for the component you wish to filter.
- Install the Filter:
- Positive Connection: Cut the 12V positive power wire. Connect the input side of the noise filter (typically marked "IN" or with a red wire) to the vehicle's 12V power source. Connect the output side of the noise filter (typically marked "OUT" or with a red wire) to the 12V positive input of your audio component.
- Ground Connection: Connect the ground wire from the noise filter (typically black) to a solid chassis ground point in the vehicle. Ensure this connection is clean and secure.
- Secure the Filter: Use the provided mounting screws to secure the noise filter in a safe location, away from moving parts or excessive heat.
- Reconnect Power: Once all connections are secure and insulated, reconnect the negative terminal of your vehicle's battery.
- Test System: Turn on your vehicle and audio system to check for noise reduction.
Note: The filter should be installed as close as possible to the noise-generating source or the component experiencing the noise for optimal performance.
Operating Instructions
The Scosche ES004 is a passive device that operates automatically once correctly installed. It continuously filters electrical noise from the power line it is connected to, requiring no user interaction after installation.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Noise persists after installation. | Incorrect installation, filter not suitable for the type of noise, or noise source is not electrical power line related (e.g., ground loop, speaker wire interference). | Verify all connections are secure and correct. Ensure the filter is installed on the correct power line. Consider if the noise is a ground loop (requires a ground loop isolator) or interference from other cables (reroute cables). Some noise, like from LED headlights, may require a different solution. |
| Audio component does not power on after filter installation. | Loose connection, incorrect wiring, or a blown fuse in the filter or vehicle. | Check all power and ground connections for tightness. Verify wiring polarity. Inspect the fuse in the vehicle's fuse box and any inline fuse for the audio component. If the filter itself has an internal fuse (not user-serviceable), it might be faulty. |
