Review on 🔊 Metra 82-3006 6 to 6-3/4 inch Speaker Adapter for GM Multi 2005 and Up by Jason Hinrichs

I have installed 6.5" infinity mouthguards with these adapters and they fit very well, the speaker holes fit nicely into the adapter holes. But once installed in the door, the end opposite the screw is not fully seated. I had to use gasket glue to keep the adapter from rattling. Next time I'll just reuse the factory speaker and cut it out to match the new speaker.
