It only happens when the car is in the on or started position

Did you run your power cable down the same side as your RCA cable?

 

[SE85VT]

no made sure i didnt do that

If a second earth made it better then check your first. Did you sand the paint back and ensure it was a good earth point? That way your bazillion max power wattage will sound fully hectic ulleh.


I did put this in all capitals, but it was auto-edited. So gay.

Sounds to me like an earth problem to.

Yeah iv tryed both earths and grinded the metal back as you cannot see it anyway because i have a coustom wall to hide the lpg tank they are both in good spots with great connection i do not know what the problem is now so not cool lol

same problem in my vy

yeah mate i have the same problem only ive kept the stock VY stereo but replaced all speakers and added 6x9s in the parcel shelf. getting the high pitched whistle only mine changes pitch to my rev's. i just tell ppl its my supercharger lol. i have been told that its most likely interference coz of my shitty stereo. hopefully wen i get my new one it goes away

Or the other option is run another earth cable straight from the battery

 

[SE85VT]
