Can you try to explain the best you can where that noise came from. Like engine noise, noise from the patch cords, noise picked up by your Antenna or Power cable, Radiated noise, Noise in the speaker wiring and Noise from the electrical system?

You could easily isolate all those annoying noise in your system w/o purchasing additional noise suppresure, but I need to know what kind of noise is these.

Hi sir thanks for your reply

My issue came from my electrical sound system. I don't know if it's from wiring/Headunit/Amplifier when my audio system starts. Just like a hissing sound. I hope you can help me on this one.
