Space-Efficient Sound Control

The Kicker 48CWRT104 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 48CWRT104 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 4-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.

Great speaker for the price

I am still in the break in period for this subwoofer, but with that said so far I’m very impressed especially for the price!

  • Installation is smoother, faster, and frustration-free
  • You get the correct accessories the first time

Whether you're replacing a factory stereo or upgrading your entire audio system, the Fit Finder eliminates uncertainty.
