About: Skar Audio DDX-15 15" 1000W RMS Car Subwoofer

The Skar Audio DDX-15 is a competition grade, 15-inch car subwoofer.

Every component used in the design of these woofers is of the highest quality for reliability and increased performance. 

Conservatively rated at a 1,500 watts peak power and 1,000 watts RMS power, this subwoofer was engineered to be extremely loud. Featuring a massive double stack motor (202 oz), 2.5" pure copper high temperature voice coil, and a competition grade pressed paper cone stitched to the high roll foam surround, the woofer comes built ready to handle serious amounts power.
