I will be building my first ported box soon and was wondering about port location? I will be using a box design that i found on SSA website for 2 Sundown SA 12's with a kicker ZX1000.1 at a 2ohm load. See the link.....

12" DUAL PORTED 4.0 ft^3 t 30 hertz

My question is , If i use this box and move the port to the outside but leave it at the same end will it change the tuning, i would think so but not sure. Sorry if i this is a stuipid question but as i said this will be the first ported enclosure that i have owned/built.

I plan on the subs firing upwards on top of the enclosure and will be pushing the box close to my rear seat. Hope i gave enough info.

thanks in advance,

If you leave the length and diameter of the port the same you can point it any way you want. It will only change things if it eats up more or less space in the box as the overall box volume WITHOUT the port has to stay the same as well.
