Who says size matters? As Kicker would like to say “all the bass, half the size.” This sub is a space saver. If you have a small trunk or maybe just a limited amount of space, but still want that Kicker sound this sub is for you. This sub also comes in 8,10,12, or 15 inches. Although the subs have the same circumference, Kicker helps you save space by flattening the sub. This allows for a shallower box in a tighter fit. A great choice for trucks or small cars.
