Car Power Filter Noise Ground Loop Isolator Car Audio Noise Filter 12V Car Stereo Audio Filter Noise Isolation Reducer for Stereo Audio Radio Amplifier Amp Speaker

Broke the engine whine that was plaguing my car’s system.

Worked as advertised

Product preformed exactly as expected. Was having alternator whine in my new stereo, and this suppressor took care of the issue.

Had a terrible engine whine after installing aftermarket head unit. Put up with it for a while. Bought these suppressors and let them sit on bench for months. Finally installed (easy installation, match colors and make sure “in and out” are in proper placement. Dang! Super clean now! Why did I wait sooo long!! Works great!!!

Bought to reduce digital noise on screen. Did not function maybe user error but seemed of good quality.

Does not suppress engine noise in radio like advertised. As engine rpm goes up the whine increases

No installation instructions for which way should be input (either from battery or radio). Tried installing both ways and didn't get rid of the whine in battery when accelerating.

Yes, I recommend it. This is a good product.

Worked well in my application, good value.

Excelente calidad y precio.

Funciona muy bien, quito los ruidos que generaba el alternador en el tomacorriente de 12v

didn't do anything to stop the static on my radio . not worth the money .

Buen producto, buen precio vale la pena cumplecon su función
