Help Building custom door panel enclosure for Componets

[SpiderCoder]

Does anybody have any suggestions on building a door panel for a componet set. I have two sets of 6.5 I took out of my altima. Im installing them in a 1994 Sedan deville and there not going to fit in the doors and im not buying new componets To much money. Since I have two pair of 6.5 almost brand new. Zapco and Diamond Hex. Thinking If my Hexes dont sell to use them as well. I dont know where to find the info for building the panel/enclosure so they sound good.
