hey i just got my 12" D2 RE SX in the mail and i will be constructing an enclosure to fit behind the rear seat of my 1995 YJ Wrangler. Ive got a Cadence TXA-1000D amp that'll power it. My dimensions will be 32x11x16 (LxWxH) with 3/4" MDF board.
This has a total gross volume of 2.43135cf^3. Here is my design:
The RE SX has a displacement of .16cf^3. With the RE box calculator the port length is 20.75. the re calc program doesnt take into consideration the displacement of the sub, so that why i am also using Quickbox elite to figure out the length of the port w/ the displacement of the sub.

the RE shows what the enclosure will look like but wuickbox will show all the correct information. The Net volume w/o the sub is 2.163cf^3 and with the sub is 2.03cf^3. RE recommends that the 12" RE SX is in a 2cf^3 enclosure tuned to 33hz.

also would it hit harder if i placed the sub in the center of the enclosure or off to the right side?

12-16 sq in of port per cubic foot
So, you are borderline. I would increase the width at least 1/4"-1/2". It shouldn't increase the port length enough to cause any problems, but it just depends on the space you have to work with.
