  1. Duke –

    Works great for car audio systems! No instructions but simple to install

  2. Tony –

    Mirrored an iPhone to my car stereo for both video and audio but the speakers picked up interference. An awful buzz and crackling sound. I installed this in line with the stereos rca jacks and presto. Crisp, clean audio with no loss of power. Best few dollars I’ve ever had the pleasure of spending.

  3. Gary –

    Great product. Easy to order online and very fast also thsnks best buy!

  4. Stiffler –

    Very easy to integrate into my oem stock system Lexus LS 400, they have things know one does!

    Installed an amp and new speakers in a 1963 car and had interference from the alternator. Plugged this in and it fixed it.

  7. Flaco10239 –

    Worked for like a minute then noise came back not for me but may work for others
    Engine whine

  8. anullsects –

    I got two of these to rid of alternator whine on my front and rear speakers. It did the job

  9. MaricopaDad –

    New car stereo had background noise – electric buzz. This simple device eliminated it entirely.

  10. Beastmode1 –

    This product did exactly what it is ment to do. Geek squad recommendation.

  11. Freezer –

    These noise canceling filters worked great. They got rid of the buzzing noise

  12. Switch323 –

    Was having an engine whining noise coming through my car speakers was installed between the head unit and the amp whine went away. Works like intended.

  13. JtDaBarber –

    Did the job and got rid of the noise. Now im at peace.

  14. Nonickname –

    Worked perfectly for what I needed. Added speakers to a wakeboard tower and there was a ton of EMI without the isolator installed

  15. ajanits –

    good product works great better if it came with instructions but google for instructions is easy enough

  16. Wires –

    Works great and great price… no problem at all I would recommend to a friend or family member.

  17. William –

    This thing works great for killing ground noise on a powered connection.

  18. Josh –

    Seems to do its job no more engine wining on my highs

  19. pablo –

    It didn’t do anything on my system so I guess my issue is somewhere else, it can pick up alternator whine noise so be carefull where you place it.

  20. nohightechforme –

    Mostly reduces the hum between an old Dual turntable with a 5 pin din connector adapter and old receiver. Not sure what to do with the two brown ground (?) wires…no instuctions.

  21. fg2dj –

    Solved my radio buzzing issue in my Honda Civic Si

  22. BayArea –

    Doesn’t work for my case to reduce noise. I end up buying a different brand/model from Amazon and the audio noise was reduced.

  23. Terrance –

    Awesome Product. Easy to use and family fun is great

  24. Nick1452 –

    Does what its supposed to if hooked up right. RCAs from your stereo to this unit then unit to your amp and as for the ground wire i just taped mine off

  25. B3ST –

    This item works great! No more headache from the buzzing sound coming from after market speakers.

  26. RonnieZ –

    I bought a couple of these to remove ground loop hum. I installed between my DJ mixer and both speakers, and audio interface which went to my PC to record sets. These did the job.

    I’ve since upgraded my gear, and now use 1) a TRIPPLITE ISOBAR surge protector with isolated filter banks to ensure good clean power to my gear, and 2) I purchased professional DJ equipment and now use quality balanced XLR cables for all connections.

  27. Dwight –

    Worked as intended, bought a cheaper version on Amazon that did not solve my ground loop issue. Works well to on Polariz RZR with ride command to get rid of the Mag ride interference. Used in conjunction with a 900 Watt 5 channel amplifier

  28. Ccmecrae –

    Really good product. Especially being that I got it at a lower price.

  29. surfahdude –

    Does it’s job. Note that it might not work for all grounding issues.

  30. gjude –

    Great product but didn’t solve my problem so I returned it. Bought to help troubleshoot my car audio problems but ended up having a different problem

  31. Unknown –

    Two of these ground loop isolators were required to knock out engine noise in my Audi A3. They really do work.

  32. SeanC –

    I had a hum and buzz in a 2005 Toyota Highlander. I installed this and it made zero difference. To be fair, maybe this works in other vehicles where a hum or buzz stem from a different reason… But in my case, it didn’t make any difference.

  33. Kristink –

    Worked like it should. Wish I had better instructions when I tried installing but that’s why we have the internet. Used this temporarily until I actually diagnosed the actual issue

  34. Applebuyer –

    So this ground loop has not disappoint me. When used right it can eliminate ground loop noise.

  35. TraylorHead –

    Great and worked perfect to isolate the tv signal. We connected the audio out from a tv to the PA system and had a lot of extra noise along with a 60hz hum. This isolated the signals.

  36. RobertoS –

    This is a good product, does what it is intended to do. Cancels busing noise on radio.

  37. ThomT –

    My car audio system was making loud buzzing noise, after bought this and fix the ground loop issue. Awesome product, works as designed too.

  38. DavidA –

    Works like it should satisfy with the product would buy again if needed

  39. Shawn –

    Great item help me out a lot no Winning sound or any feed back from my car after getting this item installed great choice, great price, and big difference in my music.

  40. LatriceS –

    I ordered online. It was ready when I got to the store. It was easy to use and worked perfectly.

  41. LouisM –

    Does exactly what is it’s supposed with easy installation

  42. GregS –

    It suppossedly works, its just not the answer for problem. But I bought it online from Best buy and showed up to get it and they were awesome and it was quick in and out. Unfortunately I’m still dealing with my ground nuke issues. I think I would pay somebody a million dollars if they could just come out here and solve it for my truck and all the money I spent on stereo equipment that I can’t enjoy really. I’m awesome at home remodeling that car stereo. I’m not so good apparently.

  43. Daurn1 –

    Added an after market amp and sub to my factory Acura radio. Had a bit of alternator noise through my speakers. Got this product and it took care of the issues.

  44. skyway82 –

    Works as intended. No more humming from my Kicker Hideaway subwoofers at low-volume levels

  45. MichaelR –

    My subwoofer had some buzzing connected this to it buzzing went away definitely would recommend

  46. MCJ197745 –

    Plugged in right behind my head unit and then ran my RCA from it to the amp. Cleaned up the low humming noise that I was getting. 

  47. MarioG –

    Bought this for the system in my suv, work as it should have

  48. KeybertM –

    It is a great item, very very useful. The ground loop reduced my motor noise in my car.

  49. KennedyW –

    Received in a timely manner with no complaints. Would recommend.

  50. Unknown –

    Garbage don’t waste your money. Much better products out there that will actually work.
