Hey,

I just installed 2 12 inch subs in my car. Everything is really tight and at normal listening volume there are no vibrations. If I turn it up really high then I can hear my back bumber vibrate. I know its not my plate, I have that dynamated. Does anyone else have this problem? How would I go about making it stop? Thanks

 

Dynamat the bumper too. Removing it isn't that difficult.

 

would it be the bumber itself vibrating or the part where it attaches to the car? is there any material you would reccommend for the part where it attachs?

 

unless your bolts are loose, it's not where it attaches. It's the big flimsy piece of urethane vibrating against the foam insert behind it.

 

thank you. ill look into this

 

Mine did that. I took the cover off and it was wicked rotten behind it!!

 

not just a little rattle i get the same thing from my single solo baric. and i changed my bumpers and its complete fine back there just take it off put it on the back on the inside of the bumper and itll stop
