if u don't have enough space then you simply cant. However, someone who know what they're doing should be able to find enuf space in that car. what kind of measurements have you taken??

Are you trying to put it in the well area? If you are it is going to be tough because i am building a ported box for 1 12" and i am having a hard time fitting it in the well of my car...
