Review on 🔌 Minimize Amp Noise with InstallGear Ground Loop Isolator by Thomas Unruh

I've tried so many of these ground loop isolators. I had a radio shop version over twenty years ago that worked great but is no longer available. Yes, I tried the new version. The build quality wasn't the same, it was cheaper and smaller and just didn't work. I've also tried some of the other major retail brands but they only acted as transmitters and boosted the signal. I ended up trying this one because it was the most similar to the one I had at the radio store. Finally, I picked a winner. There is no more hissing in my car radio. If you're desperate for a working ground loop, I highly recommend this one.
