What the heck is this? (pics)

Alright, I concluded that this has to be the cause for the whine that I am hearing out of my speaker. I ruled out these probabilities:

(Keep in mind, the noise only comes from my right speaker and it gets quieter and louder when my rpm's go down and up, the volume of the head unit has no effect on the noise, as long as the HU is on the noise is present)

-Reversing the rca input does not move the sound from left to right.

-Reversing the channels does not move the sound from left to right.

-Putting in a 2.5 foot long ground strait to the body has no effect.

-Running a new set of wires from the amp to cross over (these wires are not close to any other wire) has no effect.

-Running a new ground for the HU has no effect.

-Moving the crossover away from all electrical stuff has no effect.

That means the sound is being produced after the cross over. I attached two pictures. I don't know what is in the picture but the camera was taken from the floor pointing up underneath the dash. The wires run up along this THING and I am guessing it is the reason for this annoying whine that I am getting. If not, I am soooo fricken lost.

its your air conditioner\heater blower fan.

it pushes air through your vents to cool\heat your interior. under the fan (up in the dash) is a heatercore. wich is a small radiator. it pumps hot water thru there inline before your cars radiator to syphon the heat into your car that the engine produces. and when summer kicks in, it puts the cool water from your radiator into there to cool your interior down.

if you turn your heater\ac off... does the whine stop?

Im guessing you have a component set. Is the noise coming from both speakers on the right side?

Blower motor should only be powered up when AC or heat is on, so that might not be the cause of your problem.
