I'm knockin two 12's and i'm getting a wicked vibration coming from my third light. I don't know what to do to eliminate it. What if i stuff the light with cottonballs? what do you guys suggest?

 

I would use some rubber strips. Take the light off and seperate it and the roof with some rubber stripping from home depot.

 

Rubber strips would work if you got them in the right place. I would crank it up and then go back there and try to stop the noise with your hand. This will tell you excatly where the noise is coming from and the area you need to address. It is obviously parts buzzing up against each other so find these parts and put something in between them.

 

i put some rubber strips between the light and the window, works great! the only problem is that it looks a little shabby from the outside. i'm gonna have to find a way to camoflauge the strips so it doesn't look so tacky through the window.

GREAT IDEA, GUYS!
:hail:

 

they make a spray type foam especially for stuff liek that, try that AND try tightening your taillight screws, *****, whatever you wanna call em, ...make sure you actually have all of them on there too..
