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

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.

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

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!

I recently replaced my desktop computer, but when I connected my stereo receiver back up to the computer's audio output it produced feedback in the form of an annoying buzz and hum. I assumed I needed to replace the speaker cable with a more insulated cable, but then I read a suggestion in an online forum to try a ground loop isolator as a cheaper alternative. It was delivered quickly and I hooked it up in about two minutes. The feedback has been completely eliminated and I don't notice any reduction in the sound quality. I'm not sure if it would work in all cases, but it was a cheap, easy solution to my problem since the computer appears to be the source of the feedback.

I bought this to eliminate a very loud hum I was getting during playback from my computer based jukebox and my stereo. Between it and a UPS/Voltage Regulator, the background noise is gone!

So far its work great noise is gone great product so easy to install ground the wires and plugged in rca jacks and done listen without that noises great job

This product worked fine and solved my ground loop problem with my subwoofer. My only complaint I have is the product did not come with instructions.

Because I had a amplifier system already, this tool was necessary to keep my sound quality. The amps were factory and the radio aftermarket, not always compatible. Did a great job !

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

I had a whining coming through my speakers that I couldn't get out by changing grounds or relocating wiring. This ground loop isolator did the trick! Nothing now but great sounding music!

I have an aftermarket stereo in my car and an amplifier, the stereo has a phone setting and the people who called had to listen to an annoying squeal, now that the ground loop isolator is in they don't have to listen to it anymore. Easy installation and it worked well.

Easy to install. Works good. I have another issue so this didn't completely fix my issue.

I installed this in my Escalade to stop the feedback while the TV's were playing. Easy install works great definitely recommend.

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.

Best Buy carries high quality products and this is no exception. Great for noise from ground wire.

If you're looking at this product you probably know exactly what it's for. And this one works. That's about it.

Easy to hookup and worked great got rid of the winding noise coming from my subwoofer.

Very easy and simple to use. Noise got reduced by 80%. Unfortunately, remaining 20% still bothers me.
