Hey guys I was just wondering if I was the only one who's rear speaker deck is making an awful vibration when any kind of music is playing on the coupe? Any ideas guys?

 

Try installing some DYNAMAT.Should take care of the rumbling.

 

Dynamat helps ALOT! more than words can describe

..pestilence..

 

I had the same problem. I removed the upper trunk lining (remove push pins) and found out that problem was that the rear deck was vibrating against the sheetmetal. You can fix it by just inserting a foam or a any kind soft material in between, like a shim. There's a hole right behind the trunk light that you can insert the foam in. No need for dynamats. It's a cheap and easy fix. Now I can crank really crank the bass up. Makes a ton of difference.

I too have noticed this problem. But in my case, the rattling is coming from the rear brake light. I'll have it tighted at my next service.

 

I've noticed a similar thing in my sedan. But in my case, the rattling is coming from the rear brake light. I'll have it addressed at my next service.

 

I was thinking of Dynomat my trunk and Door, but it will add more weight to the car...

Still Thinking about it

 

I had a similar problem with a tinny vibration when playing loud tunes or going over rough roads at high speeds. It turns out that the defroster coil was loose. I had to whine and cry to the dealer for them to really take a close look but they found it. Now it's all quiet. The coil must live under the rear deck. The vibration sounded like a wire vibrating against metal - very specific, tinny, tight rattle.
