Kicker 8" Subwoofer, Thin Profile, 2-Ohm, 300W RMS, Passive Radiator

A match made in heaven...or Oklahoma Kicker's 43TCWRT82 loaded enclosure puts a thumping 8" CompRT subwoofer and a second passive sub behind the seat of a truck or in any vehicle that's low on space. The rugged sealed box was designed specifically for the subwoofer, so you can count on getting maximum performance, no matter what kind of tunes you enjoy. The second sub (called a "passive radiator") reacts to the air pressure produced by the active sub, creating lots more bass without any port noise. Big bass from a CompRT sub The 8" CompRT sub features 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 (which equals more bass) than other skinny subs. Heavy-duty enclosure Sturdy medium-density fiberboard ensures long-lasting performance from the enclosure, and its sealed design keeps the bass punchy and accurate, without getting sloppy. The enclosure's 2-ohm impedance draws maximum power from your mono amplifier.
