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.

Was having a chirping noise in my RV through the surround sound 12V speakers. Not anymore. Easy install

Very easy to install. It fix the alternator whine coming from the speaker from the aftermarket radio.

I bought two of these in hope to get ride of all the static and noise I had in my aftermarket audio system. One for my front speakers and one for my rear speakers, I wouldn't say it got rid of it entirely. But it definitely got rid of 95% of the noise. The grounds that come with it made it worse for my system, so I ended up just using electrical tape to make sure they didn't ground themselves. All in all, it worked very well.

Works perfectly! No more alternator noise! Just install between your music source and the radio input.

I was having problems with my new stereo I purchase from Best Buy and Installed myself. I kept getting feedback and distortion from the throttle. I spoke with the car audio specialist and he recommended this product. Plugged right into my rcas and fixed the problem! Thanks

This is the best ground loop isolator I have found. Works perfect for vehicles where you just can't trace the noise to the source, especially with trunk mounted batteries. Sound quality hasn't been affected by these in any installs that I've had to use them in and if you just can't find source of noise and need to resort to ground loop isolator this is by far the best product I have found.

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.

This ground loop isolator completely filtered all the electronic engine noise from the speakers 100 percent. I wired it between the RCA cables from the head unit and the crossover input.

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.

I use this to connect the audio output from a laptop computer to the line level input of the audio amplifier of a bookshelf stereo. No more 60 hz hum, and arguably it provides a measure of protection for the output/input stages of both the laptop and the stereo.

Removed that annoying popping sound instantly. Great product

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.

Good product the second one I got and both 10/10 would recommend

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

So ever since I decided to start using my studio monitors for computer speakers I kept hearing this high pitch whine every time got into any heavy workloads. Turned out it was a ground loop issue, this took care if it perfectly

I installed these with the hopes that it would eliiminate all noise, however there is still an audible “hiss” at all volumes no matter what source is used. It did eliminate a ground loop whine that I had problems locating so it gets 4 Stars.

Great product. Worked as advertised. Easy installation.

bought this item to remove electrical hum loop between laptop and mixer console caused when HDMI cables also connected in for Karaoke setup. some loss of bass end requiring EQ compensation, but not an issue.

Shop had ran my rcas right next to the power wire going to the back of my battery in the trunk and was getting a lot of noise that increased as I accelerated. Rerouted rcas away from the power wire and still had a tad bit of whining noise. Installed this and it removed the remaining noise!
