I have just noticed a issue with the front left speaker. It will happen regardless of whether the radio is on or off. It basically whistles or makes a hi-pitch whine noise at idle. It gets higher pitched if I rev from idle up to about 2000rpm after which point it goes away but will then return when the engine returns to idle.
It will not to do all the time but is rather a intermittant problem. Completely stock & untouched AU1 premium sound (with the stacker in the boot, not in-dash). Any help would be much appreciated.

I'd say something in the car is inducing in the speaker wires...
The speaker wires from from the head unit across to the left hand door... Is the computer still in passenger kick panel in AU1's? It could be the tacho wire... Hence the quicker the rev the higher the pitch... It wouldn't stop at 2000rpm... Its just so high you can't hear it... Not much you can to fix as is... This is the issue taping speaker wires in looms with other wires... Called electrical noise or induction... Way around it is to run your own figure 8 speaker cable to the door but keeping it separate from other looms... Once its in the door it should be fine... No wires in there that would cause issues... And if this still doesn't fix it... Run figure 8 with shielding and bond the shield to earth... This stops the noise penetrating the signal wire... Cheers, Tim

So I fixed this problem, I didn't really read any comments/solutions above so somebody might have said this already. We tried a bunch of things (securing ground, fiddling with cables etc.), none of them worked. So we took off the door trim and did the wire connections again, fixed it. Works perfectly now.
It's probably not the same problem for you, but it's worth a shot.
