thump. I have had the days of the huge 18" or 15" W6 in my cars, I just want decent balance, which is why I am looking for a 10". Plus, I already have a small (~.6 ft^3) sealed 10" box that fits snugly in the corner of the hatch. I have been using a 10" bazooka tube, which sounds decent, but takes up too much space and is difficult to keep secured.
