i have an 08 g35S and my front door panels vibrate when I turn the music volume above half way. This makes a crappy noise. The bass is only 1 step above mid point. Is this normal?

 

not normal but common, i spent 150 and i put dynamat on both my doors and after adding my basslink i had to do the deck too... there's a 13 inch speaker behind that door. .. ...

 

i know the actual door panels vibrate on the sweeping curve on the outer lower portion(when looking at the door panel with the door open) they almost need another pin there. it would be fixable by just making it tight with a lil bit of foam. dynamat would work too.
i noticed my bottled water will make some noise with it half full. its annoying.

 

i switched the dynamic sound option off and the vibration is gone

 

how do you turn the dynamic sound option off?

 

i think thats only in the 08's with the driver stage audio...

 

thanks kool_yarr, that's what I meant haha
