Hey Freeze!

Hmmm... I have also noticed this. One time I thought it was because I was driving fast on the freeway with the stereo cranked to about 45 on the volume and it was my door speaker ah.... vibrating. But today I noticed it with lower volume and wondered. I prefer to have diagonal windows open, driver's and back right to avoid loose papers on passenger seat from flying around or out the window. Is there a level of window height that you can suggest that would counter the whistle problem? When I am driving on the coast I don't generally use the ac because of the ocean breezes..

Thanks!!
