Hey, This is my 90 Honda CRX project I have. As far as the I.C.E. goes I own two Fusion Nv 15's, Fusion FX-45 EQ and a Jensen Flip Out. I still need to buy two NV 2500 Watt amps and a set of 3-Way components and a set of 6.5" Components. Its a work in progress. I figured I would start posting the project. It should be getting more done here soon. Here is what I have so far.
The Box in the building.

The Box all put together besides the top in the car. 8 Cubes.

Sub sitting in the ring.

Thats all I have so far. I still need a port. I tried to find out how to convert circle aero ports to a square port. Each sub calls for a 4" x 11-3/8" port. the tuned frequency is 26.2. Some help would be nice. hopefully I can update this soon. tell me what you think.

I just noticed the question at the bottom of your post.  In case you were wondering why you were getting no help, we didn't know you were asking for any.  The formula to figure out the area of a circle is  

Pie  times   radius squared.  in your case   3.14159  X  (2 x 2)    which =  12.566 square inches.   This can be achieved with a square port   4 by 3.14159  inches.     11 and 3/8 inches long.

Looks good so far. Make sure you show us the finished product. Are you wanting to compete or just have a nice stereo?

An 8cube box with NO bracing?! Other than that, looks nice.

I am guessing by looking at the speakers, 36 X 30 X  14.   On the First Gen CRX you could get 36 between the shock towers without building around them as he did.
