Apologies if i sounded offish, it wasnt my intention. I was just in a hurry at the time...
I would say its definatly not my Alternater, because i had a new (4 months ago) uprated alternator & battery to ensure i had no problems with my 2 JL 1000/1 amps (2000w rms total). I'm sure if my alternater can handle them, they could handle the less than 20w from my screen (its probably more like 5w as the whine is the same with the screen closed and just the radio or any other option on).
I am also steered away from my alternater as the whine is there while the engine is off. (I may be misleading myself on this one)
I am going to try re-earthing again, although i don't think it will make a difference as i made sure my grounding point was a good one (drilled then paint cleaned around the area then bolted to bare metal).
Something to note though, my unit comes with 2 ground cables. i presume it makes no difference grounding to the same point...? (strange it has 2 though)
OP
