Ported box design

If I'm building a box for two fi BL 15s and its going to be ported with a divider, Do I have to have a port for each side or can I put 1 port in the middle for both subs? I'm running them off two amps

Are you running one amp with the a "left" side channel rca and the other with the "right" side? The reason i ask is if you are then yes you should divide, and they should not share a common port. It would be much better though to divide the same signal and sum at both amplifiers, thus allowing you to share a common chamber, no divider needed, and common port.
