Huge value. High performance. The KICKER CompC Subwoofer pumps out the bass with all the intensity your ears can handle. Perimeter venting keeps the air free-flowing around the motor structure. With a KICKER sub that doesn't overheat, you get high-performance bass that keeps the music pounding. The CompC 12-Inch Subwoofer works best with a sealed or ported enclosure and 300 watts of recommended power.
