The Phoenix Gold ZDSW7CS is a 6.5 inch 2-way component speaker system engineered for Volkswagen vehicles. It uses lightweight glass-fibre woofer cones and 25 mm silk-dome tweeters with passive crossovers for accurate frequency separation and refined high-frequency detail. The speakers come in VW-specific mounting frames and install into factory locations without cutting or drilling, and include plug-and-play wiring harnesses for clean, direct-fit replacement while retaining the original appearance.
