New speakers don’t fit in your 2005 to 2020 vehicle? DS18’s OEMADAPT Series is the answer. This universal adapter fits your aftermarket 6.5” speakers into those 6.75” mounting spaces. (commonly found in 2000 to 2020 Chevrolet, Toyota, Ford, GMC, Lexus, Cadillac, and Lincoln models). This adapter maintains OEM-grade fitment and vibration-free stability. Its pre-drilled mounting points align perfectly with factory mounts, eliminating the need for modifications.
When upgrading to aftermarket 6.5” speakers, many vehicles require a compatible mounting adapter to properly fit within the factory enclosure, usually sized at 6.75”. DS18’s OEMADAPT bridges that gap, maintaining the integrity of your vehicle’s factory look.
Please use our Fitment Guide to determine specific compatibility for the submodel and audio features
