Description
The Metra AXGLI-M Mini Ground Loop Isolator is a compact 2-channel noise suppression device designed to eliminate unwanted audio interference in automotive sound systems. It is engineered to break ground loop paths that commonly introduce alternator whine, engine noise, or low-frequency hum into RCA signal lines. This passive isolator installs inline with the audio signal path and requires no external power, making it an efficient solution for both professional installers and enthusiasts troubleshooting noise issues. Its small footprint allows flexible placement behind dashboards, near amplifiers, or within tight signal-routing areas.

The module does not require power or configuration and can be mounted close to the noise source or near the amplifier for optimal results. It is compatible with virtually any aftermarket or OEM-integrated audio system using RCA signal connections.
