12" CompVR 4 Ohm
The CompVR 12-Inch Subwoofer is a 4Ω dual voice coil design, built for easy wiring. 
CompVR creates your bass using high-temp, dual voice coils. A ribbed Santoprene surround also gives the cone added strength under stress. The perimeter venting, Spiralead™ tinsel-lead technology, and spring-loaded push terminals are part of the high-performance engineering standards found on every KICKER woofer. 
The CompVR 12-Inch Subwoofer works best with a sealed or ported enclosure and 400 watts of recommended power. See below for more details.
