Aftermarket speakers don’t fit in your 1995 – 2021 vehicle? DS18’s OEMADAPT6X9 is the solution. This universal adapter allows you to mount aftermarket 6 x 9” or 6.5” speakers into standard 6 x 9” factory speaker openings found in many Chevrolet, Toyota, Ford, GMC, Lexus, Cadillac, and Lincoln models. Engineered for versatility, the OEMADAPT6X9 supports vertical and horizontal mounting, giving you the freedom to position your speakers where they’ll sound best. Even better—this adapter fits 6.5” and 6 x 9” speakers as shown by the reference images in the listing. No guesswork. Just a perfect fit.
Built for vibration-free stability and long-term reliability, this adapter keeps your upgrade locked in with pre-drilled mounting points that align precisely with your vehicle’s factory speaker locations. No cutting. No hassle. Factory enclosures often don’t accommodate aftermarket speaker sizes. The OEMADAPT6X9 bridges that gap—so your new speakers fit perfectly.
