My car's back windshield was broken and glass when everywhere in the car. There are a bunch of glass in my back speakers and I can't get it out. I have tired vaccuming it but it doesn't work. I try finding out where the screws that connect my speaker but unforunately it's underneath the plastic cover in my back seats. I can't play any music in my car and it's driving me nuts. I have a 03' Toyota Corolla, if anyone could help me that would be awesome!!
