8-Inch 300-Watt Thin Subwoofer Driver, 2-Ohm or 4-Ohm DVC
The CompRT 8-inch subwoofer is an all-weather thin bass driver with a pair of 2-Ohm or 4-Ohm voice coils. With a mounting depth under three 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.
An advanced suspension and heat management system helps to keep the bass powerful, deep and consistent. To make Kicker subs even more reliable, their engineers developed Forced-Air Cooling™ to help these thin subs run 20 percent cooler than before.
Kicker signature red double stitching makes an outstanding bond between the improved Santoprene surround and polypropylene woofer cone. Revolutionary SoloKon™ technology joins the cone to the vented back brace, creating a single integrated unit that both cools the motor and eliminates distortion.
The CompRT 8-Inch 48CWRT82 and 48CWRT84 subwoofers work best with a sealed or ported enclosure and 300 watts of recommended power.
