OK, So I recently aquired a 1996 jeep grand cherokee and am in the planning phase of the project. I am looking at running a 3:1 ratio 4th order with either 4 15" or 18" drivers. The issue I am running into is that I am concerned that the box height will end up too low to mount the drivers on a flat baffle. With this being said I was wondering if anyone has toyed around with angled baffles. With this setup I was going to do a driver's side port and tune around 45-50hz. Would this be too much of a hassle and prove to be a nightmare, or should I try to use a more upward firing baffle to fit the 4 drivers (similar to watt's truck but larger and drivers stacked in a 2x2 config instead of 1x4). By my figures I should have roughly 27 cubes to play with as far as interior box volume. If anyone has any ideas im all ears (i like getting loud but like lows also). Planned power is in the 15-18k range, and since my last build ran 12k and only touched 54s, id like to get as close to 60s as I can. Not really new to box building, just having "writers block". Thanks, Chris
