Great adapter to fit speakers in mount space

Worked well 07’ Suburban converting to 6.5” speakers. I needed to break off the inner tabs for it to work. Tabs have easy break cuts in them for quick conversion.

Perfect solution to adding aftermarket speakers to Chevy Cobalt. Saved me from drilling holes to mount the new speakers.

Perfect fit. No hardware included though the listing said hardware was included.

Awesome lined up perfectly with existing door panel speaker grille. It is plastic and sturdy enough to snap the smaller inserts for bigger sizes speakers to fit. Fit is great even after adding speak baffles. Awesome would but again if I need to

Fit well With some common sense how to delete tabs not needed

Pros: It fit in the door panel as it should. That's about it for this item. My car is a 2007 Pontiac G6. Had some extra tabs around the outside edge that were unnecessary, I removed those with a dremel. Cons: Didn't fit my 6.5" speaker(Rockford Fosgate Prime [...]) properly, I guess the speakers are a bit nonstandard. There are tabs all over the adapter for various speaker screw holes. All of the tabs in the center made it so the Fosgate speaker would not fit down in the adapter properly. Eyeballing the fit I thought it would be okay after removing the center tabs, but none of the screw holes lined up right with the speaker. Using the roughly 3 inch screws included in the package I rigged it up to be a solid fit. The slot holes actually helped me in this case, I feel like I remember reading some people complain about them. It took a fair amount of work and modification to the plastic adapter, but I am happy overall since it worked out in the end. Giving three stars for the required work to modify the part to get it to work. Beware of getting the 6.5" Fosgate prime's with this adapter.

Sorry as I already installed them so I can’t provide any images. But they were very inexpensive, they made the aftermarket speakers install so much easier, they fit like OEM, they are high quality, and incredibly compatible with my vehicle. Highly recommend these to make aftermarket speakers install installs so much easier.
