Product Information
Full details
The Loops Noise Suppressor Filter Box is an essential upgrade for car audio enthusiasts and daily commuters looking to eliminate intrusive electrical interference, such as alternator whine or static. It is designed for those using car radios, amplifiers, and graphic equalizers who want to restore pristine sound clarity without the need for expensive equipment overhauls. While this device is highly effective at filtering noise, it is strictly limited to 150 watts of power capacity, meaning it is not suitable for high-power subwoofers or heavy-duty audio setups.

FAQs
Will this work with my aftermarket amplifier?
It will work provided your amplifier does not exceed a 150W power draw. It is best used for head units or smaller signal components.
Can I install this on the speaker wires?
No, this device is designed for the power input lines (11-15V DC), not the high-level speaker output lines.
Does this require a fuse?
It is always recommended to maintain the existing fuse on your power line to protect both the radio and the filter box.
Is it waterproof?
No, the device should be installed in a dry location inside the vehicle cabin, typically behind the dashboard.
What if the noise persists after installation?
Check for loose ground connections elsewhere in your audio system or potential ground loops caused by multiple devices sharing different grounding points.
Troubleshooting
Audio still contains buzzing after installation.
Verify that the black ground wire is connected to a clean, unpainted metal surface on the chassis.
Unit gets hot during operation.
Ensure the total power draw of your connected audio device does not exceed 150 watts.

Setup, Compatibility & Care
Installation of the Loops Noise Suppressor involves basic electrical work. Follow these connection guidelines for optimal performance:
- Red Wire: Connect to the fuse side of your power line.
- Yellow Wire: Connect to the radio or audio device side.
- Black Wire: Securely ground this wire directly to the car radio chassis to ensure a solid path for noise drainage.
Ensure that all connections are crimped or soldered and insulated with heat shrink or electrical tape to prevent short circuits. Since this device handles DC power, avoid exposing the unit to moisture. Periodically check that your ground connection remains clean and free of rust to maintain filter efficiency.
