| whistle sound, anyone know wtf this is?
Ok, this just happens at random times and it's been happening a lot more lately, it seems to be the worst (I think) when I first turn the car on after it has been off for the night. Anyway, when I just turn the car on without the stereo or heat or a/c, I don't hear anything.
Once I turn on the stereo alone, I hear this high pitch sound like a whistle and it seems like it's coming out of the speakers I'm pretty sure. The louder I turn the music up, the louder it goes as well. Sounds simple, but it's not. It gets a bit more complicated.
If the stereo is on and I have that whistle going, and I turn on the heat or a/c even one little tick, the whistle gets way louder. Now if I turn off the heat or a/c, it goes a little quieter again.
If I turn on the heat or a/c alone without the stereo, I get the whistle....and if I turn on the stereo at the same time, again it gets way louder. So it seems like either one alone will cause the whistle, but both together make it way louder.
The worst part is that the whistle goes way louder with higher rpms. So in other words stereo or heat alone = loud ... stereo + heat = really loud ... stereo + heat + accelerating or even driving = want to rip your own face off loud.
the only thing I can possibly think of, is when I installed this deck, I know that I accidentally wired the power constant and power ignition wires backwards (red to yel and yel to red instead of r to r and y to y) so the deck doesnt keep a memory when I shut the car off. I'm not sure if those wires have anything to do with it though.....
anyone? any idea? |
