That little block is just a weight!?? I thought it was something else, don't know what, but I thought it served as some other purpose..As you add more sound deadening material to the trunk lid, I recommend removing the weight so it opens much easier. It's in your first trunk lid pic, bottom center.
It sounds amazing. I love my car and everything I have done to it so far. I get compliments from everyone I show my system to.So, how does it sound?
