The CompRT line of ultra-thin subwoofers fits under your seat or behind your back bench with ease. Now even more efficient and sporting a slick, blacked-out cone, the CompRT® gives you all the bass in very little space! The CompRT 10-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. It takes serious know-how for a thin subwoofer to deliver super-deep bass. Our signature red double stitching makes an outstanding bond between the improved Santoprene surround and polypropylene woofer cone. With our custom SoloKonT 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 CoolingT to help our subs run 20 percent cooler than before. The CompRT 10-inch Subwoofer works best with a sealed enclosure and 400 watts of recommended power. Mounting Hole Diameter (cm). Recommended Box Volume Sealed (Litres).
