Experience is on their side the gentle man who helped me was excellent an knowledgeable. They had exactly what i needed.

Great product and price! This item was exactly what we needed and did the job well. Don't hesitate to make a purchase I'm sure you won't be disappointed.

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.

I had a terrible ground noise in my home amplifier and between grounding the amp and reciever together and using this device my problems are solved.

For whatever reason connecting my amp directly to the head unit causes them to go into protect immediately. So I installed these and fixed the issue. They sound really good. Unfortunately one didn’t work and I had to replace it. Also they seem to have really poor isolation. Placing these anywhere near a power cable from the vehicle caused a terrible ringing in the tweeters. This happened with my heated seats, turn signals. Etc. I really had to find an isolated location for these.

I would hear sound out of speakers whining pitch louder as the car accelerates from my Pioneer stereo and stock amp. This took it away

Hard to fine, literally called a store that specializes in DIY (do it yourself) fixing technology and they had no idea what I was talking about and told me to check Home Depot. I needed this because of a "Hmmm" noise coming from a car sub woofer I installed in my home. The aux from this device is connected to my television, while the output is going to the cars audio amplifier. The ground wires from this device is also connected to the amplifier in the ground terminal. Problem fixed!

Awesome Product. Easy to use and family fun is great

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 !

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

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

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!

Does as listed, Gets rid of unwanted amp noise from power wire and RCA wire close together.

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

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

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

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

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.
