Worked well, removed tabs 07 suburban
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.

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

Perfect fit as an adapter for OEM speakers on my Silverado!!
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.

Required modification, and the speaker still didn't fit
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.

Le quedaron muy bien a mi Chevrolet Ónix 2021, solo hice uno que otro ajuste, un cortecito y fue todo para que quedaran bien

Used to make the install of new speakers in my 2010 sierra bolt in... kicker DS speakers bolt right in, and then the bracket fits perfectly in the doors of the truck... the 7mm factory bolt fits perfectly and the bracket even gives you 2 more mounting holes if you want to use them. I did and used small self tappers.

Las usé para Buick Encore y Regal. En ambos casos fue necesario cortar las pestañas ubicadas en los laterales medios, que están diseñadas para poder cortarse casi con la mano sin romper o afectar el resto de la pieza. Sugiero aplicar un anillo de silicon negro (o flexible) en la parte trasera para evitar vibración. Fuera de eso la pieza es excelente.
