Review on 🔌 Minimize Amp Noise with InstallGear Ground Loop Isolator by Edgar Gomez

This product works well. I have a (4) channel 1400w car audio amplifier and it had some noise from two front and two rear speakers. I bought one of these for the two front speakers to see if it would work and it removed most of the noise. So I bought another one for the two rear speakers and the noise was completely gone. The sound quality of my stereo does not seem to be affected. The only thing is that the input and output of the product are swapped/swapped. When connecting to your amp, simply plug in the RCA connectors that match your amp and plug the other end into your stereo. I think the manufacturer just taped the packaging upside down.
