Space-Efficient Sound Control

The Kicker 48CWRT102 is an elite 10" thin-mount transducer from the CompRT series, meticulously engineered to provide a substantial low-frequency foundation in environments where space is at a premium. With a mounting depth of less than three-and-a-half inches, it is the ideal solution for under-seat enclosures or the restricted space behind a pickup truck's bench. This all-weather driver features a blacked-out SoloKon polypropylene cone and a UV-resistant Santoprene surround—reinforced with signature red double stitching—ensuring it maintains its acoustic integrity and mechanical poise in demanding mobile or off-road conditions.

To sustain high-output performance in a compact frame, the 48CWRT102 utilizes Kicker’s Forced-Air Cooling technology. This system uses the cone’s own motion to actively cycle air through the motor structure, allowing the subwoofer to operate 20% cooler than standard slim-line designs and preventing thermal compression. With a Dual 2-Ohm Voice Coil (DVC) configuration and an impressive 400-watt RMS power rating, this 10" driver offers the installation flexibility and mechanical authority required for sophisticated, space-saving high-fidelity audio systems.

Impressive little sub

Good sounding and powerful little sub! I’m running dual subs wired to 1 ohm with a Kicker 800-watt amp, and they really pound in our old school C4 Vette.

Just a heads-up—do your research on pricing. After I bought mine, I found them cheaper elsewhere.
