When i have my stock sub turned up and i am listening to a a song with some heavy bass. Sometimes as rattling comes fromthe rear deak where the sub is mounted and i cant seem to find the source that it is comeing from. I know this has been brought up before bu ti cant seem to find any posts about it. Also just to make sure it wasnt my trunk i adjusted those black stopers to make the trunk shut tight.
Well i appreciate any help that i can get. Thanks again.
