Hi, I've got a set of Sony separate component car speakers that have spent more time in the box than in my car. I was gonna put them in my new car but after careful inspection I discovered the rubber surround between the cone and the metal cage of the speaker is coming away. It just needs re- glueing. I was wondering if anyone else has had any experience repairing this problem, and what type of glue should I be using ? keeping in mind the glue needs to handle a bit of heat over summertime in the car.
