Review on 🔌 Minimize Amp Noise with InstallGear Ground Loop Isolator by German Diaz

I installed a subwoofer, speakers in the doors and 2 amplifiers on my truck. I also installed a cheap 10.1 inch Android head unit. It sounded pretty good, but it made a horrible generator hum. This made it impossible to hear the system at low volumes. I didn't have high hopes for this $10 filter but figured it was cheap enough to try. Perfect. The amp now plays crystal clear, without hissing, howling or anything else. Just a nice dead quiet noise threshold. No noticeable impact on output or sound quality. Note, as another reviewer pointed out, the label is upside down. The RCA plug is connected to the amplifier and the RCA cable coming from the main unit is connected to the socket.Installed in less than a minute and 100% solved my problem.
