Now even more efficient and sporting a slick, blacked-out cone, the CompRT® gives you all the bass in very little space! The CompRT 8-inch Subwoofer is an all-weather thin subwoofer with a pair of 2-Ohm voice coils. 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 our subs even more reliable, KICKER engineers developed Forced-Air CoolingT to help our subs run 20 percent cooler than before. Our signature red double stitching makes an outstanding bond between the improved Santoprene surround and polypropylene woofer cone. Revolutionary SoloKonT technology joins the cone to the vented back brace, creating a single integrated unit that both cools the motor and eliminates distortion. The CompRT Eight-Inch Subwoofer works best with a sealed or ported enclosure and 300 watts of recommended power.
