I didn't think the M-Audio subs were good enough to cause plate rattle. Maybe I should test mine out.i put dynamat on the back of my plate (both front and rear). rear so it doesnt vibrate from the m-audio subs... but front so when i install it for long road trips i do not risk damaging/scratching anything.
I've never had a front plate on - & here it's required.I am relocating to a state with front plates. I am so no happy about this.
May I suggest this solution? Really worked well for me...Where can I get a licence plate bracket. I live in a front plate state as well
NYPD can be a pain with it, but in LI they got better things to do. I have been stopped but they just run my license and tell me to put it in on the windsheld. knock on wood
