Re: 18 in the trunk?
i can see it working, i was planning on doing an 18 in my trunk before i got a zcon 12 and my car's a tiny 03 corolla got 6.2 cubic feet with some adjustments worked out. it'll be a lot less then the optimal size but its still in the workable size where it wont sound terrible. Your trunk has a lot more clearance compared to mines.
