Every adapter is laser-cut from solid acrylic to the exact millimeter for your specific tweeter. Select your tweeter brand and model, or choose your cutout size in millimeters if you already know it. No measuring, no filing, no Dremel work - it drops in and fits perfectly.

Mounts in the factory tweeter location using factory hardware. Your trim pieces reinstall exactly as they came from the factory. Works with both Bose and non-Bose equipped Silverado and Sierra trucks.

Sold as one pair. Tweeters not included. If you are not sure which size you need, select "Not Sure" and we will contact you before shipping to confirm the correct cutout for your tweeters.
