Audio Noise Filter for Radio and Intercom - by Rugged Radios

Eliminate noise issues in your communication system with the Audio Filter!

Note: For vehicles with Active Suspension, use our Active ISO Filter.

This inline filter suppresses common noise generated through the charging system and power supply in most cars.

Alternating current fluctuations from any electrical components/accessories contribute to communication noise and disruption. Using the simple plug-and-go Audio Filter improves your communication for both your intercom and/or radio!

Compatibility: Compatible with most Rugged Radios and intercoms. For waterproof radios, including M1, ABM25, and GMR25 use the Waterproof Audio Filter.
