cant hear it at low volumes, it happens every time when first playing a song then about after a song or two it goes away, usually when i turn the volume up the static gets louder then eventually goes away.
check see if your wiring is secured to speaker,and amp,also...a friend of mine had a set of rcas that were touching metal,causing a fading out issue, so he wrapped with electrical tape to solve the issue..try those first, and let us know what you found/or if the issue still proceeds
na the speaker wire is all wrapped in electrical tape, i think it the amp itself, i wrapped the rcas and it didnt help i also switched the rcas and that didnt help,i will do more testing tomorrow, i going to go right from the radio to the amp that runs the door speakers and see if its still there.
