Fiberglassing wheel well

I am very new to this fiberglassing concept, and this is my first time posting on this site but let me first congratulate all involved in this site for a job well done. This is my dilema. I would like to create a Sub box in the wheel well area to house two 12" alpine SWR-1241D that require between 0.7-1 ft^3 each of volume. How would I go about building a fiberglass enclosure in the wheel well creating an enclosure that has two separate units for each Sub thereby given the required volume and getting maximum performance. I am planning to do this in a Nissan Sentra 2004.

Hey, go here http://www.geocities.com/MotorCity/7165/how_to_1.htm this guy did really well with the instructions and layout. Then I would just add a piece of 3/4 MDF in the center to seperate the 2 sides as well.

i would suggest a larger space for those subs, more like 1.25cu ft or 1.5cu ft
