CompRT 12" thin-profile dual voice coil subwoofer — 2 ohm (48CWRT122)
The Kicker CompRT 12" is a shallow-mount subwoofer built for tight spaces without sacrificing output. It is an all-weather sub with a mounting depth under four inches, UV-resistant cone and surround, and dual 2 ohm voice coils — making it suitable for a wide range of vehicles and conditions.
A thick magnet structure delivers high power handling without adding mounting depth. The UniPlate™ back plate and solid pole piece act as a single heat-absorbing unit for effective thermal management. SoloKon™ cone technology and the CompRT's unique framework keep the sub slim while maintaining low-end performance. Kicker's Forced-Air Cooling™ system helps the sub run 20% cooler than previous designs.
Features
- Shallow mounting depth
- Small enclosure requirements
- Forced-Air Cooling™
- Signature double red stitching
- Push terminals

About the Kicker 48CWRT122
From our tech experts at CEN
A 12 inch subwoofer from the Comp line, Kicker’s long-running range for solid bass without a competition budget, with a 2 ohm voice coil so it can be wired to suit your amplifier.
Who it suits
Drivers building a system where the bass does real work rather than filling in behind the speakers. It needs an enclosure sized correctly for the driver: sealed for tight and accurate, ported for louder and deeper.
Our tech experts advise
A subwoofer is only as good as its enclosure and the amplifier behind it. Box volume, port tuning and how the voice coils are wired decide what you actually hear. We build enclosures to suit the vehicle and match amplification at our Beeston workshop. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.
