2003 Honda Odyssey suffering from a massive static noise after I install a Boss amplifier, I already install a noise suppressor to the constant and accessory power terminal of the head unit and I already tried grounding the RCA connector plug. But it only lessen the static noise by 80%. The 20% remaining is still very annoying you can never lower down the volume if you do you will automatically hear the static whining noise..... I'm skeptic at first to try this RCA type noise filter but at the same time I'm already desperate. anyways upon installing.... BOOM !! ... the noise is totally gone! All I can say is try it ! if it doesnt work for you ..you can always return it. .... The only thing like is when I bought it last week its $6.46 each .. right now today its only $4.50 :(

I have a decent audio system in a 1999 Dodge Ram 1500. That's Pioneer Nex HU, Alpine digital amp, Focal Flax components x2 and a JL sub. Everything worked perfectly for a couple of years until I completely sound proofed the extended cab. That's when the wandering buzz, crackling and hum started. Along the way I did upgrades to an AGM battery, big 3 and a HO alternator. I rechecked all the grounds several times, unsuccessfully searching for the problem. My HU has the pigtail RCA harness so the copper wire cure wouldn't work for me. So I went to Amazon read a lot of reviews on various Ground Loop Isolators. I chose InstallGear because of their reputation for providing quality parts. I'm glad i did. Turned out I needed a filter on every channel, but all of the now the annoying sounds are gone. I'm so glad to hear clear, clean and loud again! Thanks InstallGear😎

At the end of the day, it helped noticeably reduce the engine whine in my new car audio system.Now here's the backstory if anyone can relate:A year or so ago I had an aftermarket car stereo installed in my project car, 2002 Celica GT. The new stereo was nice, but it had no balls. So about a month ago I bought new speakers for the front (Rockford Fosgate component) and the back (Kicker full range 2-way), and a new class D amp (Jensen). Also, a powered subwoofer which has its own channel on the head unit. Did all this work myself with some help from my brother who had just done this in his Camry.Long story short, I couldn't get rid of the engine whine (buzzing sound that changes with the RPM's) no matter how many different ground configurations I tried. So this was a last resort quick fix that I did hoping just to hear an improvement. My expectations were not high. The noise reduction is absolutely noticable, and I am very pleased. The hum/buzz is still there, but it's only about 30% of what it was before. It's easily 70% gone at this point.*I should say that in addition to this, I also applied 3 clip-on magnetic ferrite noise filters to the stereo's Constant (power) wire (purchased separately).One last point: I'm a big do-it-yourself guy, so I'm going to keep tweaking the system and looking for ways to eliminate the noise altogether. However, I am not a professional which is evident by some of the other glitches I'm seeing in my newly upgraded system. At some point, I am probably going to take it in to a professional to have it fine tuned and all the little bugs removed.Moral of the story: Do it yourself if you can. If you find out later that you can't, and you have the money, take it to a professional.

I installed an aftermarket stereo in my car, and it had an annoying popping issue when I turned the car on or off, switched radio channels, etc, since my car's factory speakers have their own amps. I got 2 of these (each of these has 2 lines, so can solve 2 speakers) for my car's 4 speaker setup, and it immediately solved the popping issue.The problem is that the plugs are incredibly cheap, and one of these leads broke off inside of the rca plug for my stereo's wiring harness. In their defense, i was fitting it in a tight space, but it still snapped off way too easily, and now I cant even plug that speaker into my stereo. Its not the end of the world, since I will end up cutting off the leads and soldering it together, but still, no reason for the leads to be so cheap

I installed a subwoofer, door speakers and 2 amps in my truck. I also installed a cheap 10.1" android head unit. It sounded pretty good, but had terrible alternator whine. It made it so the system was unlistenable at low volume.I did the normal troubleshooting of checking my grounds, making sure the RCA didn't cross paths with any power wires, used a nice shielded RCA cable, nothing would get rid of that awful whine.I didn't have high hopes for this $10 filter, but figured it was cheap enough to give it a try. It worked flawlessly. The amp is now playing crystal clear with no hiss, whine or anything. Just a nice dead silent noise floor. No noticable impact on output or sound quality.Note, as another reviewer pointed out, the label seems to be backwards. The male RCAs plug into the amp and the RCA cable coming from the head unit plug into the female end. Installed in less than a minute and solved my problem 100%.

Struggled with buzz, hum and what sounded like line contact issues after getting new laptop for my PA. Tried everything, and I mean EVERYTHING else. I have been DJ'ing and hosting Karaoke for 37 years and this is the first time I had encountered ground loop issues, so it never occurred to me to ask the RIGHT question; I just kept trying to fix things I was familiar with. Finally did a search and just asked the internet what was wrong without telling it what I thought it was and finally got the right answer: Ground Loop Interference. 24 hours later, I have the InstallGear Ground Loop Isolator Amp Noise Filter connected and everything sounds clear and perfect. I wasted months because I was too stupid to ask for directions and got lost and frustrated for my troubles.

It doesn't cut the noise when the audio is Playing. I connected it even serially and checked but nothing works. It just cuts the noise when nothing is playing on the car stereo.

I had interference in my boat when i was using the trim switch so I bought this device. After I ‘ve installed it the interference was worst and I had no more bass in my 6x9. Took it off and trowed it in the garbage….
