I have an 06 altima and i just put a double din DVD player up front. and im getting high pitched noises out of it. My ground is good, clean and secure. So i started looking at Altima forums and noticed quite a bit of people coming up with the same problem. And i noticed that alot of them blame ElectroMagnetic Frequencies for this problem by saying there are alot of electrical items behind the dash that interfere with the radio...
For instance if im sitting in my car with the engine off just playing the radio theres no noise. but if i turn my headlights on (which are factory HID's) i get noise...
So basically im asking:
1. If anyone on this forum may have run into this issue with their altima and if/how you went about resolving it. AND
2. Can these "EMF's" really be interfering with the radio.
And all the speakers are the stock BOSE which i had no noise issues with before installing the aftermarket deck.
