About the Helix CI41663
From our tech experts at CEN
The Helix CFMK165 VW.7 is a pair of FlexMount165 adaptor rings for the factory rear woofer position of the Volkswagen T7. They let a 6.5 inch (165 mm) Helix Compose midbass fit the original mount, with speaker gaskets and mounting material included. Speakers are sold separately.
Who it suits
T7 owners, including camper converters, who want better sound for rear passengers. It works with the Ci7 W165FM-S3, Ci3 W165FM-S3, Ci3 W165FM-S2 and the woofers in the Ci3 K165.2FM-S3, K165.2FM-S2 and C165.2FM-S3 sets.
Our tech experts advise
This ring is for the rear woofer position of the T7, not the front doors. Rear speakers are best kept lower in level than the front stage, which a DSP makes easy. Installation is priced per vehicle, so contact us with your build year and we will confirm fitment.
