Default new box for 2 hdc3 12's?

I currently runnin 3500d on 2 hdc3 12 copper d1's in box designed by chris at fishercustoms.com. It sounds good on any music, but doesnt pick up the lows that much. The box I have now is subs up, center port firing back tuned to 36 hz. I believe he said its 4.25 cubes net with like 65 square inches of port. I have up to 49" wide x 36"D x 18"H. Any suggestions on tuning lower or building box smaller? Pm me if you can do design and how much

check your SSF first as that box should drop plenty low...

placement sounds fine. Could try moving it closer to the hatch and see if that changes things..

thanks mlstrass, ssf was a little high, I changed that, and seems to have helped a good bit. I am running these until they sale so really dont want to bother with new box now.
