    I checked all my connections, added 2 more grounds to my head unit and amplifiers but the wine/buzzing sound never went away. I installed 3 of these filters on my RCA outputs in between my Radio and Line Driver. The Noise Went Away!!! Finally!!! Thank you!!!
    Highly Recommend!!!

    And for those of you amateurs that don't know what you're really doing... stop blaming the product. That's just dumb and irresponsible to the next person. Terminate your fiber optic system!!! If you remove a component such as your CD player and don't terminate that port, this will not work, and it shouldn't!!! That's how Fiber Works! If you don't know, then educate yourself! And anyone complaining of it popping at startup or shutdown... wire up the remote line, Dummy! That's like plugging in a guitar with the amp already powered on! And for those complaining of ground hum noise... stop listening to the know-it-all experts - running a separate ground. NO! Ground it with your stereo ground. Keep them the same. Just use your regular old ground at the stereo for both. They don't need a monster sized ground cable like you're powering a freaking nuclear station. Chill!!!

    1.0 out of 5 stars Absolutely kills lows but did remove the noise.
    Reviewed in the United States on October 23, 2023
    Verified Purchase
    I originally bought these to help with some alternator wine in my mids/highs. First, I rerouted all of my RCAs down the opposite side of the car from the Amp wires (Electro magnetics is a real thing). After relocating the RCAs the wine was gone from the mid/highs amp but then I noticed a low hum in the subwoofer amp when connected to the RCAs. I attempted to use one of these in line with my JL audio 500/1. The Noise was gone but I lost about 70% of the output of the amp. I had set the 1-ohm load to 24v. After installing one of these noise isolators the output voltage dropped to 7v. I could not turn the gain up enough on the amp to match my other amp.

    5.0 out of 5 stars Alternator whine
    Reviewed in the United States on November 29, 2023
    Verified Purchase
    Added a cheap 4 channel amp to a truck with headunit, sub and amp installed. Had ground noise and alternator whine. Cleaned and checked ground connection, swapped rcas still no change. Plugged filters in between amp and rcas. Removed the alternator whine I was expecting. It does mask some of the voltage so gains will need adjusted accordingly.

    2.0 out of 5 stars Quality control?
    Reviewed in the United States on September 17, 2022
    Verified Purchase
    This GLI fixed the problem on one side but made it several times worse on the other. At first I chalked it up to a wiring issue on my end to give the product the benefit of the doubt, but I have known good RCA connections on the head unit and the amps, and known good RCA cables. After verifying all of my ground connections, the problem persisted, and when I flipped the RCAs the problem went to the other side. If it were my connections the problem would have remained on the side with the poor connection.

    The product is potentially worth a shot but just keep your expectations low. Looks like it works well for some people.

    It didn't come with any instructions, so I may be using it incorrectly. However, with the ground loop isolator in place, a new, louder buzz is being generated. Needless to say, I removed it and will be finding a new solution.
