About the Helix CI42009
From our tech experts at CEN
The Helix CFMK20 FOR.1 is a pair of FlexMount20 adaptor rings for Ford vehicles with a factory-fitted tweeter. Each ring takes a 0.75 inch (20 mm) Helix Compose FlexMount tweeter and holds it with a snap lock in the original mounting position. Tweeters are sold separately.
Who it suits
Ford owners replacing the factory tweeters without cutting panels or making brackets. It suits the Ci7 T20FM-SC, the Ci3 T20FM-TI, CB T20FM-S and the 20 mm tweeters supplied with Helix sets such as the Ci3 K100.2FM-S3.
Our tech experts advise
Check that your Ford has a factory tweeter in the door or dash before ordering, as the ring needs that mount to fit. If you are changing the door woofers too, Helix also makes the Ford-specific CFMK165 FOR.1 midbass adaptor. Installation is priced per vehicle, so contact us with your model and year and we will confirm what it needs.
