Review on 🔊 Upgrade your GM Speakers with SCOSCHE SAGMHR634B 6.5” or 6.75” Adapter Pair by Brandon Mcvey

I don't understand how they fit any speaker from 6.5 to 6.75, only 5.0 inch internal horn spacing, 6.25 inch outer diameter. The speakers are 6.5 and protrude about 3/4 inch above the surface they are to be mounted on. I'll try to sand down any inner tabs and see if they can be used. They are cheap and come with no instructions or screws. Beware. Update Date: I was able to adjust them to fit. I snapped out any internal protrusions and smoothed them out with a dremelin. Use small nuts and bolts to connect them with only 4 connection points that fit. These were 6.5 inch Pyle speakers. The adapters appear to have been made primarily for much smaller speakers than those advertised.
