Not too surprised about that, usually license plate mounts/frames are the initial cause of rattling with subs since there's almost always a bit of 'play' with them.


Have you decided what you're going to do to secure the plate?

Just do this please, remove your license plate and you will see the that the vibration is still there. As I mentioned in my initial post I already took care of the plate - small pieces of foam between plate and car. Now when the volume is above 25 I go outside to see the actual source of vibration and rattling and believe me is not the plate.

Yup, that's what the solution is across the board.

Some guys even put a small black rubber washers inbetween the screen and plate along with locktite for the screw so it doesn't loosen due to vibration. Just throwing that out.

Although I don't consider this a personal problem since I seldom turn up the volume past the middle, I am interested to know how this eventually results in a resolution for Dmitri. Kennedy mentioned about rubber washers. I was going to suggest the same.perhaps rubber washers between the body and license plate would do the trick. A more sturdy plate frame might help also. The one the dealer installs is flimsy. I am thinking of replacing mine.

I just booked my next service ( 8000km) for June 1.
I mentioned to them my sub rattling concern, so I will keep you posted.
BTW, I don't know about US but here in Canada the first two services are free of charge :-)
I am thinking this is probably a small compensation for the absence of Lexus Enform in Canada -which is ridiculous and stupid!!

Starting to think a lack of sound proofing material to fill up inside the panels might be a reason for the rattling, sometimes that needed with installing aftermarket systems.

what if you go louder, drown it out perhaps?

Is it possible to easily add some noise cancelling foam or something like that where you hear the rattling coming from? That doesn't seem like it should be too tough a task to take on yourself.

It is, and quite easy, all a matter of removing panels that are in problem area's and applying an appropriate amount of sound proofing.

The lazy way is to shove something, like a folded up tissue in a gap from a problem panel
