Lifting off my speaker grill and looking into the hole there appeared to be a rolled up paper receipt, i tried to grab it but it felt like part of the car and was rolled/fixed there.
Its on the passenger side, i did take the speaker out and tried to grab it but it was wrapped securely around a metal frame. I can't imagine the manufacture leaving something in there.
Ah well, it will remain a mystery unless I tear it free :-)
