Kicker 12" 4 Ohm 1000W Peak CompR Pro Car Audio Subwoofer Black 48CWR124

• The CompR 12-Inch Subwoofer is a 4 dual voice coil design, making it easy to get the most out of your amp.
• An advanced suspension and heat management system helps to keep the bass powerful, deep and consistent. Revolutionary SoloKon technology joins the cone to the vented back brace, creating a single integrated unit that both cools the motor and eliminates distortion.
• To make their subs even more reliable, KICKER engineers developed Forced Air Cooling to help our subs run 25% cooler than before.
• The CompR 12-Inch Subwoofer works best with a sealed or ported enclosure and 500 watts of recommended power. See below for more details.
