If you're looking for bass for a tight space, Kicker designed their CompRT subs with compact cars, pickup trucks, and ATVs in mind. The low-profile 48CWRT84 8" subwoofer performs just like a full-size sub, but without killing all your cargo space. This high-performance CompRT sub stands less than 3" tall, so your installation options are wide open.
