Exactly what i was looking for

Needed a bracket for my new car door speakers and these fit perfectly in my 2008 Chevy Cobalt. Very easy to install. Very happy with the outcome.

Works in my 2010 Silverado.

I used these adapters to install my old MB Quart 6 1/2" separates. They did the job. I put these adapters over some Stinger Roadkill that I used to deaden the doors with. I felt like some sort of material between the adapter and the door was necessary. I don't know that to be true, but can say that a good tight fit was obtained when I did. The clip at the bottom and one screw at the top kept the speaker secure. There is a place to utilize a couple more of self tapping screws if you feel the need.

Does the Job

The fit was nice and it looks good. The only problem is the pocket. It was slightly warped in the middle giving it sort of a lip. I had to super glue it to get it so that there wasn't a lip. The pocket also didn't want to lock in to the tabs that are there for it to snap into place. I've experienced this in the past with kits from Scosche that have the pocket. Metra makes one piece models for some vehicles, which eliminates the problem with the pocket.

Makes speaker installation much easier.

I used to just drill holes in the door and mount the speakers straight to the door, but the steel in the doors is thick and has a rolled edge, which makes drilling the holes very tricky and time consuming. These brackets mount just like the factory speakers, fit nice and tight, and space the speaker out some, which makes them seal against the back of the door panel, for better bass response. The other manufacturer's bracket is flimsy, only snaps in, and just does not work as well. I have used these quite a bit, and highly recommend them. Installing speakers in these trucks without these brackets is doing it the hard way.

Great Buy!

I bought these adapter brackets to install pioneer 6 1/2" speakers in front and rear doors of my 2007 GMC Sierra NNBS. These made the install super easy. They are a perfect fit. Great price. Great product. Buy these. You will not be disappointed.

Perfect for 2011 Buick Regal

Just what I needed to add aftermarket speakers to my 2011 Buick Regal. The stock midrange speakers are glued to the original mounts. These are a perfect fit and leave the originals as is to put back in the future. BTW - Infinity component speakers are a great fit and sound awesome. They come with a tiny Infinity emblem that I hot glued to the Tweeter grills. Nice custom touch! Now there is no distortion when cranking Rock. It actually sounds better with the bass turned down to almost flat, now that it has real speakers instead of the cardboard junk from the factory.
