Covers both tweeter and mid-range locations on the Corvette C6 and select GM vehicles. Every adapter is laser-cut from solid acrylic to the exact millimeter for your specific speaker. Smaller sizes (35-51mm) fit tweeters, larger sizes (52-79mm) fit mid-range drivers.

Select your speaker brand and model, or choose your cutout size in millimeters. No measuring, no filing - it drops in and fits perfectly in the factory location using factory hardware.

Sold as one pair. Speakers not included. If you are not sure which size you need, select "Not Sure" and we will contact you before shipping.
