2) KICKER 10C12D4 12" 800W Dual 4-Ohm Comp Car Audio Subwoofers Subs+Sealed Box

The Comp is loaded with many of the innovations found in elite KICKER woofers, including the stiffest injection-molded cone with flex-killing, 36-degree back bracing, updated coil-cooling perimeter venting, high-temp voice-coil wire, and Spiralead tinsel-lead technology for ultimate durability. The Comp is also versatile, performing in vented or sealed enclosures, and in free-air applications as well.
The Comp makes perfect sense for any factory upgrade. With easy-to-use, nickel-plated push terminals, a resilient, updated steel basket, and yellow double-stitched surround, the Comp looks as good as it sounds.
