rattling of window with sound system
 

Hi,

I'm from Hong Kong so some of the specs of my JDM lexus might be diff from the US.

2004 RX300, with Mark levinson and No navigation.

when bass is turned to medium, i get a rattling of the driver side window that is very noticeable....any idea which part of the door or speaker assembly is worn out and needs replacement for this kind of rattle?
