ok so im building a box for my 2006 bmw sedan. Im making it fire straight thru the ski pass. imma mount the box on to a mounting board that is completely sealed air tight from the cabin to the trunk. i was wondering if different dimensions produce different sound quality if the cu.ft is the same. for example lets say the dimension is 14 in wide and and 14 inch height and 7 inch depth is .6 cuft (just making this up) and another box 13w and 13h and 8d and is also .6 cu ft. would there be a difference with the sound. i was wondering what would be the best dimension for a sealed box for my sedan for a kicker L7 10 inch 4ohms if i want like very good sound quality with some loudness. does the depth of the box make big difference wen it gets longer or shorter?
