About the Helix CI42007
From our tech experts at CEN
The Helix CFMK20 VW.2 is a pair of FlexMount20 adaptor rings for the factory tweeter position in a range of Volkswagen, Skoda and Seat vehicles. It takes a 0.75 inch (20 mm) Helix Compose FlexMount tweeter, held in by a snap lock. Tweeters are sold separately.
Who it suits
Volkswagen, Skoda and Seat owners fitting 20 mm Helix tweeters such as the Ci3 T20FM-TI or Ci7 T20FM-SC. If you want the 1 inch (25 mm) Ci5 T25FM-CA instead, look at the CFMK25 VW.1, which takes both sizes.
Our tech experts advise
Volkswagen group cars use more than one tweeter mount, so check your model before choosing between the VW.2 and the CFMK25 VW.1. Fit the tweeter so it clicks home fully, then test for buzzes before the trim goes back on. Installation is priced per vehicle, so send us your make, model and year and we will confirm the correct ring.
