Kicker 48CWR104 CompR 10" Subwoofer, Dual 4-ohm, 400w RMS The Kicker CompR subwoofer is the name of durability and dependability. The CompR is back with some nice new upgrades to elevate the durability even more. The new Forced-Air Cooling keeps you playing hard and longer by lowering temperatures within the motor by up to 25%.
