Kicker 12" 4 Ohm 1000W Peak CompR Pro Car Audio Subwoofer Black 48CWR124

Kicker 12" 4 Ohm 1000W Peak CompR Pro Car Audio Subwoofer Black 48CWR124





Now even more efficient and sporting a slick, blacked-out look, the 2021 CompR sub is the very model of power and reliability.





12" CompR 4 Ohm - The CompR 12-Inch Subwoofer is a 4 dual voice coil design, making it easy to get the most out of your amp.





An advanced suspension and heat management system helps to keep the bass powerful, deep and consistent. Revolutionary SoloKon technology joins the cone to the vented back brace, creating a single integrated unit that both cools the motor and eliminates distortion.





To make our subs even more reliable, KICKER engineers developed Forced Air Cooling to help our subs run 25% cooler than before.





The CompR 12-Inch Subwoofer works best with a sealed or ported enclosure and 500 watts of recommended power. See below for more details.
