Just got my 2004 Xfire about a month ago and that RATTLE is driving me nutz same exact place!!!

As soon as I reach over and place a lil pressure on the door it stops!!! Second I let go it starts ... Can't even enjoy music in the car.

My Xfire was purchased used so I am sure they are going to fix it at MY own cost if I bring it in...

Any advise would be great!!! RATTLE IS DRIVING ME INSANE... SOUNDS AS BAD AS A BUSTED SPEAKER WHEN BASS HITS !!!
