The red rubber surround is a signature design of all Cerwin-Vega Mobile subwoofers. The Vega Series 10 in. 1 100 Watt DVC Subwoofer also features a robust proprietary stamped cast Vega basket. Couple that with a parabolic 1-piece stamped carbon-fiber polypropylene and a high- single-stacked motor structure and some serious boom will be protruding from your trunk! For installation ease an integrated impedance selector feature has been added to keep system wiring simple. And that signature red Santoprene surround now incorporates matching red double stitching to complete the finish.
