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 48CWRT102 10" subwoofer performs just like a full-size sub, but without killing all your cargo space. This high-performance CompRT sub stands less than 3-1/2" tall, so your installation options are wide open. Kicker has redesigned the forced-air cooling system, so this sub will run cooler when you drive it hard.
The 48CWRT102 comes equipped with a rigid injection-molded polypropylene cone that won't flex and cause distortion while you're cranking the bass. Its rubber surround will last through years of heavy use, combining with a special-design back and top plate to give you more excursion than other skinny subs.
