What in the rear of the Cobalt is the most rattle? It isn't the license plate.

Looking for input from the audio gurus who turn the Cobalts into bass cars.

I just have two 12s pushed by a 1000watt amp nothing major, just want that rattle taken care of. Doesn't sound good on the outside.

I think it's something above the fuel cell by the rear bumper...maybe a support?

I had a horrible rattle and it was those anchors for child seats or whatever on the rear dash... The tabs just pop right out, and i have never had a rattle since!

It's not coming from there I removed almost all that except what I need for my son.

It could be the panel in the back hitting the rear window, just my guess. I put some towels under it and I'm pushing 2 12's with 2000watts and rattles except for the rearview mirror.

anytime you put a system in your car it is gonna rattle if its anygood. go to local electronics store and get some dyno mat or i think tsunami makes some as well thats cheaper. apply that to the trunk or get a spray on dampener and spray the trunk , should help alot

What rear view mirror?

When I am pushing my system it knocks my mirror off and into my cup holders. Tightening the screw does nothing...I need to loctite the SOB. But yeah when my stereo is thumping I can't focus on objects in the rear view so I just use my side mirrors.

i used 100 sq ft of dynamat in my trunk, completely stripped the interior and did it too, and i still had horrible rattle, i took my system out and gave up

All that money down the drain whew.

100 sq ft. I do not want to know the amount that was.
