Compact Acoustic Performance

The Kicker 48CWRT84 is an elite 8" thin-mount transducer from the CompRT series, meticulously engineered to deliver a rich, foundational bass response in environments where traditional drivers cannot fit. With a mounting depth of less than three inches, it is the ideal solution for under-seat enclosures in compact vehicles or behind the bench in pickup trucks. This all-weather driver features a blacked-out SoloKon polypropylene cone and a UV-resistant Santoprene surround with signature red double stitching, ensuring it maintains its acoustic integrity even in the rigorous conditions of off-road or marine installations.

To ensure consistent performance during high-output sessions, the 48CWRT84 incorporates Kicker’s Forced-Air Cooling, which allows the motor to operate significantly cooler than standard slim-line designs. By utilizing the movement of the cone to cycle air through the assembly, this system preserves signal clarity and protects the internal voice coils from thermal fatigue. With its Dual 4-Ohm Voice Coil (DVC) configuration, this 8" driver provides the system-building flexibility required to achieve a precise impedance match with high-performance mono-channel amplifiers.
