Fits 2024 Colorado Bose rear doors
Fits a 2024 Colorado with Bose system for rear doors. Need to modify the screw hole. Elongate the hole work fine. Fits 6.5 inch aftermarket speakers.

Fits newer GM
These fit my 2025 Sierra 1500 elevation non Bose stereo. I cut the two tabs on the outside to be safe bc my OEM bracket didn’t have them.

Fits 2023 GMC Yukon!
Perfect fit on my 2023 Yukon XL rear doors with the Pioneer TS-Z65F speakers which are a bit larger than standard 6 1/2” JL C1 I had in there before.

Only fits FRONT doors for 2008 GMC Sierra 1500 Extended cab
Only fits FRONT doors for 2008 GMC Sierra 1500 Extended cab. The description is incorrect. These did not fit the rear doors in a 2008 GMC Sierra 1500.

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.
