Well my current box is ported, the guy who I bought my subs kinda set me up

He told me to take 2 3" pipes that are 4" in length and install them.... I am guessin he was way off then lol....

I am thinking about going back to a sealed enclosure, so I think I am going to cut my current box down to a smaller size I had been given a dept of 9.75 for the setup on a sealed box for the 2 subs so I think I will try this to the box I have, so I would just cut the 15" down to 9.75 and reface the box so its sealed and see how it works, dunno how stable the box will be in the car without the risk of tipping sicne I dont really have anplace to securly mount it..... May make a MDF spare tire cover yet and mount it to that.... but I have nothing to loose, I want trunk space so i will try this first....
