Enlarge your horizons with bigger bass
Kicker's CWRT672 loaded enclosure puts a low-profile 6-3/4" CompRT subwoofer and a second passive sub in a downward-firing box that brings Kicker bass power to the crowded spaces of today's cars and trucks. The rugged sealed box was designed specifically for the subwoofer, so you can count on getting maximum performance whatever music you listen to. The second sub (called a "passive radiator") reacts to the air pressure produced by the active sub, reinforcing the low end without the noise of a ported enclosure.
Made to dish it out
The CompRT sub's tough injection-moulded polypropylene cone gives it the stiffness to resist distortion when you're pushing the volume. Its rubber surround stands up to heavy use, and combines with a specially-designed back plate to give you more excursion (which equals more bass) than other skinny subs. This sub handles up to 150 watts RMS, so you'll get the kind of bass response that brings the best out of your music.
Good-looking and tough
The box's downward-firing design helps protect the sub from damage, and lets you place items on top of the cabinet to save space. Its sturdy medium-density fiberboard construction and rugged black carpet covering give the enclosure good looks that complement its performance.

Features
Woofer & Passive Radiator: The Kicker 48TCWRT672 enclosure is loaded with one 6.75" (6-3/4") CompRT series subwoofer. The Kicker subwoofer features a polypropylene cone with a Santoprene surround. The surround and cone are attached using Kicker's signature red double stitching, providing an outstanding bond. Along with the subwoofer, the 48TCWRT672 features a 6.75" Kicker reFLEX passive radiator, providing extremely low bass from a compact sealed enclosure.
Forced Air Cooling: Kicker uses their SoloKon technology to join the cone to the vented back brace, creating a single integrated unit. This forces air through the motor assembly allowing it to run 20% cooler and helping eliminate distortion.
Truck-Style Enclosure: The sealed enclosure is made of heavy-duty MDF (Medium Density Fiberboard) with extensive internal bracing, providing exceptional acoustic efficiency and deep powerful bass. The enclosure is covered in sleek black carpeting for added protection and a refined look. Its compact, truck-style form allows it to be mounted behind bench seats, in cargo areas, or under some seats firing upwards.
Speaker Terminals: A single pair of spring-posts are mounted on the side of the enclosure in a recessed terminal cup, and will accept pin connectors, single banana plugs, or bare wire up to 10 gauge.
Power: The single 2Ω CompRT subwoofer can handle 75W-1500W RMS (300W peak).
Break-in Period: Due to the complex nature of Kicker CompRT speakers, they require a break-in period in order to produce optimum low-bass response. The suspension system is very stiff out-of-the-box. Approximately two weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. Once broken-in, the subwoofer will exhibit stronger bass performance, smoother response, and greater low-bass extension.

Replaced a vented sub with this sealed unit and I will never go back to a vented sub. Tight controlled base small size (reg.cab p/u) and fair price. Couldn't be happier.
