Who had ported there rear deck . and also does it makea noticeable difference in sound or vibration. I just took my rear speakers out and I took off the grills and well it may be louder its hard to tell but how do i make the damn deck stop rattling.
And also does any of you have a problem with the whole damn car rattling? i have things under my car rattling, the fin the license plate, i think even teh muffler is now. Oh and my controls for my sunroof vibrate badly and the sunroof cannot be open while listening to my system cuz it just vibrates and flops so much. \
Has anyone been able to stop all this vibrating?

 

The only real solution is to park the car and turn it off. But there are a lot of different materials that can be used to damp resonation.
