Thanks for the replies. The resaon I asked this question is because I want to put a subwoofer box in the back. I figure that I can get something that sounds better and is cheaper than the shaker1000. Would it be possible to fit a box that is 38"wide, 8" High, and 14" deep in this car? I have no seen the trunk yet, so im unsure of the space. If this box would fit, would it be hard to put it in and take it out of the car? I would take it out to go to the track.
