When i am Driving around on rough pavement at like 25 to 40 mph, my car Rattles alot, it squeaks also from the back. i only have about 1k on the odometer. Is this normal, and anotherthing thats been getting on my nerves is this jet engine like sound that can be faintly heard. I figure the turbo but to make sure is that normal?

The Squeak is like Uber annoying.

 

The only noise i get is when i have all 4 windows rolled down, the 3rd brake light cover rattles...it also rattles when the dual 12" woofers kick some bass...

 

The Cover rattles, maybe i can put some felt under it. Thanks
