12″ CompRT 2 Ohm

The CompRT 12-inch Subwoofer is an all-weather thin subwoofer with a pair of 2-Ohm voice coils. With a mounting depth under four inches and plenty of power handling, this go-anywhere sub is as flexible as it is powerful. A UV-resistant cone and surround help make the CompRT sound great wherever the road (or trail) takes you.

A thick magnet structure reliably delivers huge power handling without affecting mounting depth. The specially designed UniPlate™ back plate and solid pole piece serve as a single heat-absorbing unit to provide excellent thermal management. With our custom SoloKon™ technology and the CompRT’s unique framework, the sub sounds fat – but keeps it thin! To make our subs even more reliable, KICKER engineers developed Forced-Air Cooling™ to help our subs run 20 percent cooler than before.

The CompRT 12-inch Subwoofer works best with a sealed enclosure and 500 watts of recommended power. See below for more details.
