Found out the hard way...I built the vented ED spec box (2.2 @30Hz) for my 15a. The size of the box will fit in the trunk, but it is imposible to get the box INTO the trunk. Now I need some custom plans so I can make another box that will fit into my trunk. I am willing to pay for some plans (esp. cut list) to the same size and tuning, just different dimensions so it can fit. The box would need to be about 16 inches (is the okay for a 15 inch driver?)in height. No more than 28 inches long (preferable about 26 in). I am trying to build this box ASAP. I am also a beginer in building so the easier the, the better. Shot me a PM if anyone is willing to help.
