Attached is a picture of the 8" sub in my 2014 Azera. I am wondering if anyone can tell me what the heck the foam cover on the top is for. My first suspicion was that it was intended to be some type of vibration stabilizer between the sub mount and the grill. But the dang thing doesn't work that hard, so now I'm wondering. I'm also asking the question because that cheap paper cone is destined to seek other employment this weekend, and I am wondering if I need to keep it when I put the new woofer in. Thoughts?
