Hi guys,
Here is the link to the pics of how I made my f/g kick panels (without having to troll through pages of text on forums):

Definitely check out the fabrication/installation section on caraudioaustralia as they have heaps of links and useful tips which can speed up the learning process. It is not really that hard, just messy and time consuming. That is why a pair of custom kick panels (like the ones I made) would cost around $800+ if they were made by a car audio shop (yes a reputable shop gave me that estimate after seeing the finished product).
If you are carpeting over them (or even vinyl) instead of paint, it will save you hours and hours in paint prep as every little pin hole has to be filled before paint goes on.
Good luck - shoot me a U2U if you have any specific questions - unfortunatley I don't have the time to help in person but I'm happy to help with advice/questions etc.
