Installing aftermarket speakers
2015 Chevrolet Equinox
Holes lined up fine but be sure to measure your depth. I still had to use spacers to install my 6.5" speakers with this adapter. Then had to deal the gap with duct tape or expanding foam to get the bass I wanted.
Pros: Holes line up with existing so you don't have to strip anything.
Cons: Mounting my 6.5" speaker required some customization and glue and the bracket isn't threaded.
