## Customer Reviews

### ⭐⭐⭐⭐⭐ Removed audio alternator sound heard in the speakers
*by J***O on April 5, 2024*

This actually removed the ground loop sound I had in my speakers. Have two amps in the car and when adding a second amp the sound started. Tried with one of these and sound still there but when two were used one for each amp. The whine sound is gone! The only little con which is not a big deal is you have to adjust your amp settings these lower the sound a little but other than that great product!

### ⭐ Horrible item. Extremely inconsistent
*by E***O on July 30, 2023*

I bought this item to remove all the buzz and whine from my alternator in my cars high amp audio system. I’m running about 1500 amps to my speakers but this shouldn’t matter because its just an input device. After playing load for 10 seconds the audio just cuts off and won’t turn back on. If I want to play my music I have to cut power to my amps which requires me to turn my car off which I’m not going to do on the freeway. Don’t buy if you plan on playing loud music for more then 10 seconds.

### ⭐⭐⭐⭐⭐ Works like a charm
*by P***! on May 29, 2023*

Supper easy to set up. Just plug in and go! Was tired of listening to the whining and buzzing by my sub and half rack so I bought this and it worked perfectly!!
