Ive started a new box for my solo x's and ive made the port as it was before and putting it in the middle but i might change it to full length of the box across so the subs are split from each other as this port allow 1 inch gap either side.
My system contains 2 x 12" Kicker solo x and a mtx thunder series 4000d run at 1 ohm, followed by my KQ9 equalizer by Kicker.
I got quite alot done on the build yesterday box is nearly built but as for the resin is takes ages to complete as every angle needs to be done for major strength and to seal it.
Ive got the Port complete sprayed it black before i install it into the box so it looks dark into the box alongwith the floor which also sprayed black.
Next thing is to screw and glue the bottom along with resin the bottom also, create another top piece flush to the side of the c pillars and cut it bigger than the diameter of the subs so theyll be flush mounted once in. I also making sides for the box so its flush all the way round to the boot of the car and ive got a little trick to do on the front of the box when its comes to fabrication process.
