[HELIX CFMK80-100 | Ci5 M80FM-S3 80mm to 100mm FlexMount Adapter (Pair)]

The HELIX Ci5 M80FM-S3 is an 80mm midrange unit, but in some vehicles the factory speaker mounting space is closer to 100mm in size. The CFMK80-100 is a dedicated FlexMount adapter that lets you fit the Ci5 M80FM-S3 into these 100mm mounting locations without forcing the installation.

Key Features

• Adapter that fits the Ci5 M80FM-S3 (80mm midrange) into a 100mm mounting space
• Sold as a pair (set of 2), so both left and right sides can be fitted together
• Makes it easier to consider a trade-in installation that keeps the factory speaker position

Before You Buy

The CFMK80-100 is the adapter only - the Ci5 M80FM-S3 speaker itself is sold separately. Whether it can actually be installed depends on the vehicle, model year, and the factory speaker specifications, so we recommend consulting with us and checking your actual vehicle before purchase.
