hello to everyone on here this is my first time using this website one of my friend told me that he gets all his info from here and the other users on here. So ill just let you guys hear my problem and maybe you guys can help me, ok last night i was driving and i can hear this crazy sound coming from the back only when i have my back windows down and when i put it up i dont hear it, it sounds like i got a subwoofer in the back but i dont; i turn off my radio and drive on the highway and it sound nasty its like a vibrating noise and before i take it to the dealer i rather hear what you guys have to say. oh by the way i have an 06 acura TSX

 

Umm, are you sure it's not just the wind resonating in the car when your windows are down?
