Car Radio Power Noise Interference Suppression Filter 20A

Eliminate unwanted electrical interference in your vehicle with this 20A noise suppression filter. If you have recently installed a new radio, amplifier, or other electronic equipment and are experiencing persistent engine whine or alternator noise, this filter is designed to suppress interference entering through your device's main power supply.

Important Troubleshooting Note: Before installing this filter, please ensure all earth/ground points on your radio, amplifier, and antenna are secure and making a solid connection. Please note: This device only filters noise present on the main +12V power input. It will not eliminate noise induced via signal paths, such as RCA cables, speaker leads, USB cables, ignition input, light input or antenna leads.

Professional installation is recommended to ensure correct wiring and safety.
