And for the record... I did recommend a flat wall over a 4th given the same cone area //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif however 8 15s is more than can be fit properly in a flat wall in his vehicle due to baffle size. The cone area alone should justify going with a 4th. A 6th would be nice but it would be near impossible, if not impossible, to get enough space. The 4th is already a tight fit
