Exactly what i was looking for

September 20, 2013

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.

Does the Job

June 4, 2013

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.

Works in my 2010 Silverado.

March 10, 2014

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.

Makes speaker installation much easier.

August 18, 2013

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.

Perfect for 2011 Buick Regal

August 28, 2012

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.

Great Speaker Replacement Adapter!

August 26, 2012

You require these adapters to place aftermarket speakers in the doors of some vehicles. Including Pontiac G5s WITHOUT the Pioneer sound system. My G5 has a Pioneer sound system now :) I had to trim off the screw mounts around the edges to fit the door panel back on seamlessly, but otherwise this is exactly what I needed, and probably what you will need as well if you drive these vehicles. It is possible to modify your original speaker mounts, but this is a far less labor intensive option, and you retain the option of placing your original speakers back in your car.

Fits Perfectly

April 2, 2015

These worked great in my 2010 Silverado. The only down side is cutting out the tabs when installing 6.5" speakers. They cut out easy enough with diagonal cutters or wire snips. I would highly recommend these to anyone with a newer model Silverado.

If you have one of the cars that requires this adapter, nothing else comes close. The fit is perfect. It makes a good seal out of the box and requires no drilling as it has tabbed slots for screws in all applications.

Front speaker mount

September 6, 2019

These brackets are the way to go. I used pioneer aftermarket speakers and if you use aftermarket speakers to use the original brackets you have to saw around where the speakers set in and cut the wiring. With these and wire connectors to match it plug and play and make install simple did both sides in 15 minutes. Hope this helps

I wanted to replace my door speakers in my 2007 suburban. The factory speakers molded into the bracket. So I thought I was going to have drill the speakers into the door to install them. Right before I was preparing to do that,sonicelectronix popped in my head and I said let me check to see if they make a replacement bracket for my truck. Bam! They sure do! Saved me a lot of time and money! They fit perfectly.

They were included, but...

April 15, 2016

Purchased some JBL speakers to replace the fronts on my Chevy HHR. This is such a common problem that Chevy should offer to replace them with an upgrade, or send each owner some kind of cash incentive. However, these parts came with NO INSTRUCTIONAL guidelines! BAD IDEA to the manufacturer and the company selling it. After pondering the options available, I chose one and drilled two small holes and mounted them securely and vibration proof. Added about 30 minutes of brain and buying time. After mounting the first JBL speaker in the housing, and replacing the difficult on the HHR door panel, the sound incurs no rattle, with solid Bass and clean highs. Good bracket which would be excellent if there were any guideline as to installation.
