Jaycar Response Ground Loop Isolator – Stereo RCA, Hum Eliminator

That low, persistent hum sitting under your music in the car? It's a ground loop. Two devices sharing an earth path, fighting each other, and turning your stereo into a 60Hz drone. This isolator breaks the shared ground at the RCA connection, kills the buzz, and leaves your audio clean. Stereo, plug-in, done. If the hum is stubborn, try earthing one of the brown ground wires too – that combination nails it in most installs. It's on our shelf, ready to ship

• RCA stereo format – drops directly into existing wiring
