Hello, I will be installing some Focal 5.25 components in the stock door locations of my Corrado. Does anybody have any tips to maximise their SQ? The stock design fits in a plastic mount on the door skin and the magnet resides in a cutout through the sheet metal of the door. A vapour barrier has a pocket where the magnet would sit. Should I cover the sheet metal with sound deadener. Should the door panel be reinforced in any way? Thanks, Bob.

As much sound deadener as possible,inner skin outer and door panel.
