Not saying that the product does not work but I couldn’t get it to take away the noise go away. Im not very versed in this area technology & my equipment is VERY old.

Sounds like a good idea but these things do not really work tried it in many different locations right behind the radio etc etc did absolutely nothing come to find out it was my RCA cables

This actually somewhat worked, It got rid of most of the noise. I can still hear some alt noise but its very minimal.

Not sure if I’m doing something wrong or not, but when I ground the 2 wires on the isolator to my chassis, it makes the noise louder.

DS18 , NF1 removed the noise from the engine sound, but the white noise increased
