I have two 10" DC Audio lvl 4s with XL soft parts that I am wanting to put in my Ford Ranger super cab. I haven't decided on an amp yet, but want somewhere around 2k RMS. I just need to know about how much airspace each of these will need as well as port length and area. There is a bit of room to work with as I am taking out one of the back seats and plan on going up all the way to the rear window with the box. I calculated internal airspace after driver displacement to be somewhere around 2.6 cubes if I just build the biggest box possible. Surely somewhere around that area will be good after port displacement. I am open to using aero ports as well. Any help would be appreciated.
