Ok this is weird. I have the 2 12" subs in the trunk and they bump and no rattles since i put weather striping behind the license plate and that stopped that. NO rattle most of the time, but the little times I want the attenstion and roll down my windows and blast the bass like no other....

I get outside my car and i can hear rattling under the car near the trunk... what can it be? Its not the Exhaust...so i cant find it... any ideas?

 

ok nevermind, I put a blanket in the spare tire and that stopped most of it. You can delete this thread...
