The KICKER® CompVR® Subwoofer gives you incredible b4ng for the buck. Emphasis on b4ng! To get the most out of your amp, every CompVR comes in two or four-ohm dual voice coils. Our red surround stitching binds the suspension perfectly to the cone, while SoloKon™ marries the woofer and back brace into one, cohesive system.
