Im having a weird cabin noise in my 05 RL... when i open the door it goes away and when i close the doors the noise comes back. it sounds like its coming from the subwoofer in the rear and sounds like a faint "bass" noise thats not turned all the way up even though the radio isn't on. wtf is going on??? its getting very annoying please help

thanks,
John

One of the mics may have gone bad.
