rattle rattle rattle
 

I recently got my system ( 2 12 " eclipse ) it make my hart shake but also my back window windshield wiper thing.

the 2 12" are located in my used to be called trunk, so i dont have any ideas in how i can make the rattle stop, from the inside i cant hear it but if i step outside i can...

i was thinking taking it off, what you guys think of that?

any ideas plz let me know

I'd say before you take the wiper off, you should try and put some sound deadening on the inside of the hatch. I haven't gotten around to in my scion so I'm not sure how to take the body panels off, but if you can get the inside of the hatch off, put some dynamat extreme-like product on the sheet metal and that should do a good job of reducing most of the vibration, which should in turn stop the wiper from bouncing.
