Yep, dont even have a plan. no designer on here feels confident enough to make me a design. so ill build the biggest enclosure i can and see what fits. The 18s "can" use so much space, that your going to have a hard time making an enclosure too big in that car, just once it's done, try to figure out the volume, then make your port. It surely wont be too big. if i can get 18 cubes ill run 3 18s if not ill have a very efficient wall for 2 18s. ( I bought 3 just incase) Oh man, I bet you wish you could see the look on people's faces when they read that. Ha didnt think of that. im nobody special, if i can afford them... They really arent that expensive. No I agree, CA just pulls in a lot of young people with no money and really shouldn't be spending all their money on subwoofers, so it's extremely expensive to them. Where as if they were an average person with a steady income, then it's really not that much.
