With my stereo in my car when its turned up my spoiler like vibrates is there any way to tighten or stop it from making the sounds?

 

Sure it's the spoiler? To check you can take off the plastic on the underside of the hatch and check to make sure everything is tight!

 

Yeah, as Brent said just make sure everything is tight, I would think it would come from the license plate more than the spoiler cause the spoilers are usually decently tight on there, but if in fact it is maybe even some sound deadening material?

 

ive heard of this issue, but yes i agree usually license plate or rear bumper...

easy fix is buy some gasketing material... remove spoiler and lay a strip down on each side where it attaches...also put some on the back of the license plate incase it is vibrating
