[HELIX (Audiotec Fischer) FlexMount200 CFMK200 POR.1 | Fits: Cayenne 92A/958, E3K (9YA/536)] A pair of FDM 3D-printed adapter rings that mount an 8-inch (200mm) HELIX COMPOSE woofer into the factory woofer position (front door), with waterproof/sound gaskets on both faces and mounting hardware included. Confirmed to fit vehicles with both the standard and BOSE factory sound systems.

*This is an adapter ring only - a woofer (e.g. from the HELIX COMPOSE range) is sold separately. As it has no purpose on its own, installation labor will be quoted together with the separately purchased woofer.

*This is a provisional price pending final purchase-cost confirmation.
