About: Skar Audio DDX-12 12" 1000W RMS Car Subwoofer
The Skar Audio DDX-12 is a competition grade, 12-inch, dual 2-ohm or dual 4-ohm, car subwoofer. The DDX line-up was engineered by Skar Audio to be a SPL grade woofer that could also be utilized in daily system applications, allowing non-competitors to use the same subwoofers as those competing in the lanes. The DDX-12 is equipped with an advanced air flow cooling system to help dissipate heat, enabling it to provide continuous reliable power.
Conservatively rated at 1,500 watts peak power and 1,000 watts RMS power, this subwoofer was engineered to be extremely loud. Featuring a massive double stack 202 oz motor, 2.5" pure copper high temperature voice coil, and a competition grade pressed paper cone, stitched to the high roll foam surround, the DDX-12 comes equipped ready to handle serious amounts of power.
