so, I picked up some new car speakers for myself today, they fit in the same screw holes at the factory installed ones the only issue is that the originals had a plate on them which covered some space, the new speakers do not have that so there is a gap between them and the panel. With my basic sound knowledge I would assume this void drastically hurts the output of the speakers as the pressure pushed forward just goes back behind the speaker, or would this gap have a minimal effect? What would be a good way to fill it without damaging the speakers and not looking horrible. ( A simple and cheap solution would be ideal)
