Help with Porting

[Iumio 0]

Sup guys, first time poster. I have a 2003 dodge dakota regular cab. I have 2 SSD 10" that I have in 2 sealed boxes behind the seat. I am looking to take one out and put 1 ported box for only one sub in. I have the box dimensions that I want just can't figure out where to put the port or how big it needs to be. I have a HiFonics 1600 mono That I am going to be wiring to the sub at 1 Ohm. The box dimension I have came up with will give me 1.25 cubic feet @33Hz.

Height = 15 inches

Width = 24 inches

Depth = 6 inches

Please help with port size and location

Why do you want to take one out and port the other? Also, I assume you have dual 2 ohm coils? Were they just wired at 2 ohms at the amp and not giving all of the power the amp could provide?
