Hashim bhai, it was good talking to you a while back about the pw show. I might need the mf cloths in a couple of days when I come back to islamabad. will let you know before hand though.

Its not the window thats rattling. Chances are its your trunk and rear speaker shelf that are the culprits. These are made out thin metal sheets and cause rattling due to the sub. Its called metal flexing. Make sure its the trunk and the rear shelf because the windscreen is never the culprit. Atleast not on a new car and not when you are running a single sub.
The way around this is to sound deaden the rear shelf and trunk. Get 2 Sheets of sound deadener ( Stinger Roadkill, Lambo ) and cover the rear shelf and underside of the trunk.
