This bundle includes two Kicker 45L7R124 12″ Square Dual 4-Ohm Subwoofers. The 12-inch L7R Square Sub moves more air and delivers bigger bass than circular subs, so you get more bump out of every watt! It’s simple – more cone means more air moves. KICKER’s L7R Square Sub technology gives you up to 20% more cone area than a round sub. Full 360-degree back bracing keeps the entire cone strong and stable for smooth, distortion-free bass. The L7R’s powerful motor delivers big bass, while utilizing next-level thermal management for optimal performance. The UniPlate solid pole piece & backplate construction ensure the sub stays cool, even under extreme power loads. Dual voice coils come standard on all L7R models, for ultimate wiring flexibility. Get the highest possible power out of your amp.
