The CompR 8” Subwoofer is a 2-Ohm dual voice coil design, making it easy to get the most out of your amp. Our 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 until 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.
