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.

As long your vehicle does not have an excessive about of poorly grounded components. Grounds should be clean and tight before a device like this is used as a bandaid for the real problem. However, it serves it's purpose when you can't find the source of the interference.

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.

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

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.

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.

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.

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.

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.
