I'm about to get a couple subs from a friend, and I was just wondering if anybody knew what it is that causes that horrid trunk rattle. I've noticed a few cars around town with systems that I'm sure cost a lot of money, but they just have that God awful rattle like a woodpecker is hammerin away at their car with a screw. Sub quality? Enclosure quality? I just need to figure it out before I get mine installed. Also, which boxes do you guys recommend? Or should I just go with custom work?.....I'm gettin an NES put in there somehow. Even though I have a PS3, I have to pull out the classic.

 

Most likely it's that plastic interior piece on inside of the hatch.

 

It's called "bass"

haha, seriously though, we have a bunch of panels that vibrate, the spare tire/jack will vibrate if its in, tail lights, all sorts of stuff. It is hard to get a card that doesn't vibrate at all. You have to do a pretty good job sound deadening to eliminate all of the rattles, but if you do, your system will sound 10x better.

 

put dynamat on stuff, it will still rattle, but you wont hear it

 

Or you can buy a good product like Second Skin or RAAMat

 

put a strip of weatherstripping around your license plate then screw it back down. that causes alot of the sound your describing everytime it hits

 

For me its the tail lights. I can stand behind the car and push on them when the bass hits and it stops most of the rattles for me. The next biggest one sounds like a heat shield or something. Perhaps the sheet metal guard on the gas tank?

 

DYYYnNAAAAA MAATTTTTT to the rescue. That **** is nuts, they showed a bell and it would ring like it shoould
then put a small peice of dyna mat on it
and it wouldnt do anything but a dull thud.

 

i put dynamat in mine, but it still rattles the outside... when i oush in the tail panel ( the panel people make into a berger) the rattling stops.. i dont know how i can secure it but it makes it osund like **** from the outside

 

I had this problem also, turned out to be the tail light on one side was missing the screw backing to hold it in place. Other than that, Dynamat (ignore the rhyme).
