are you going for good sounding or just high SPL?

there are plenty of box design programs that you can use if you have the specs of the sub.

Personally, I just build a box to what I feel would be good, then fine tune the port afterwards. But I have been building boxes since 1992.

I would put the subs on the passenger side and the port on the driver side, make the port as high as the box (12" if the box is 12" high) Then do the width about 10" and length of 16". Then I would shrink the port area or length as I see fit.

Or I would use a 10 or 12" round flared port and adjust the length to fine tune.

This is how I build sometimes and it always works for me.

i m wanting 140+ but i want it to sound good
