Well i have fell in love with your wicked one design. i built one for my frinds s-10 and its relly loud. i used 2 cheap-o sony subs. ( Frinds request ) he came to me with them and said make these loud so i tryed one of the wicked ones. it was vary loud for what they were.
But now since i have seen the potentail of a wicked one i have decided to build 4 of them and stack them up in a wall in my van. i have a 1986 GMC Safari van. and from roof to  floor its 4.5 ft exactly so i figure 4 of them should fit right up in there. and the 36 in x 36 in ones are perfect to because 36in is the length form my back door to my 2nd row seat lol. and the 36in wide would ma ke it perfect for leaving me room left for a amp rack.  I will post pictures as i go of me building the wall. also i will be Running Funkin Audio SX 10's in side the WO's with a MutherFunkin 800 to each pair. (close to 2000Wrms @1ohm) i am hopen to break a 150 while playing music in iasca. and take win some 1st places in iasca bass boxing. i relly hope that this will all work out. is there anything that i could do to tweek the sound of the WO's like rounding the ports. also i would like to know if it would be ok if i use partical board anf put a coat of fiber glass on the entiere insie and out side of the box so it is vary vary smooth. ( the reason im thinking partical board is because its 9.99 a sheet around my house. and mdf os 22 a sheet. or wouldi be better off youseing some kinda 3/4" plywood.and can i use poly fill in the seal part of the box? to make it seam a little larger to the sub. i have found out that the Funkin Audio sx line like larger boxes...

here are the subs im going to use
