Features

Overview: As of 11/6/13, the SAGMHR634 is compatible with select 2005-2014 GM vehicles. The bracket is designed to allow easy replacement of the factory speakers with select aftermarket 6-1/2 and 6-3/4 speakers. (Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.)

6-3/4 Speakers: For a 6-3/4 speaker to fit in the opening of this bracket, the tabs around the inner speaker opening will need to be removed. They are scored along the bottom for easy removal, but still may require pliers and a file.

5-1/4 Speakers: While a 5-1/4 speaker will mount easily in this bracket given the bolt pattern, the frame of a typical 5-1/4 is approximately 1/2" smaller than the opening in the bracket, making a 6-1/2 or 6-3/4 a better fit. When using a 5-1/4, a speaker baffle must also be used to seal the rear of the speaker.

Dimensions:

  • Outer Diameter: 6.375"
  • Inner Diameter: 5.663"
  • Height: 0.85"

Long lasting and durable.

Written By Dealbreaker, Florida on Sunday, February 22, 2015

Crutchfield Customer Review (What's this?)

I actually have two pair of these brackets, one from a previous installation and one the I received free with the purchase with a pair of speakers. They are tough and they fit my car perfect, and they are so snug I could barely put sound dampening material around them. Quality buy. Make sure you don't get two pair if you're buying speakers at the time, because Crutchfield will send you some freebies and you can save $12 bucks.

Pros: Strong and durable; you only need one pair for the life of your car unless you total the car.

Cons: None they fit snug and make using Dynamat aroud them a challenge. Try a sound dampening paste for permanent options or don't even use anything it won't effect the sound too much I'm just an avid listener.

Close, but still useless.

Written By CCHRST310, INDIANA on Sunday, February 22, 2015

Crutchfield Customer Review (What's this?)

This is surely a quality produce and you can't beat the price!. They fit in my 09 Sierra well, although about 3/4 of an inch more shallow that the factory bracket. My issue was the bracket was to small for the 6.75 RF speakers (Rockford Fosgate Prime R165X3 6-3/4" 3-way car speakers) I purchased. Like James in Calif, I resorted to removing the factory from the original mountong bracket and tie wrapping the new speaker to the old more substantial mounting bracket. To bad GM can't make speakers to match the quality and durability of the bracket they put the $3 speakers in!! Despite the xtra efforts the speakers are great, trhe service was quick and the cost unbeatable. Anybody nees 4 of these brackets?

Pros: Price

Cons: Not a true match to the speakers I purchased.

Crutchfield Customer Review (What's this?)

Could not use in my 2008 GMC Sierra. The speakers mounts were about a half more shallow than the factory speakers and I could not get a good seal with the door panel that allowed for the sound to project through the door panel. I utilized my dremel tool to cut the speakers out of the factory housings and tweaked them for use with new speakers.

Crutchfield Customer Review (What's this?)

The brackets work and fit well in the door of my Silverado. My biggest concern is how sturdy the connection of the my polk DB651 was. They were mounted to the bracket with just four short screws through a very thin mounting hole in the bracket. I would like to see some more positive contact with the hardware to give my a better feeling with how these speakers are held into the bracket

Pros: They work....

Cons: Concerns about integrity

This speaker adapter was included with my order for Infinity 60.11cs speakers to go in my '13 Camaro. They certainly fit in the door opening of the car but it fits much looser than the factory speaker and is constructed of extremely flimsy plastic.

Pros: Fits my application

Cons: Flimsy material Fits loosely in door opening of '13 Camaro

The speakers mounted up to the bracket alright, however, the mounting screws stripped out with very little pressure.

Pros: Bracket fits in the door properly.

Cons: Need to include small screws with lock washers and nuts for mounting speaker to brackets. Need to include more detailed instructions for mounting speakers to bracket.

Crutchfield Customer Review (What's this?)

Perfect fit. Had to use long screws. It did not seem to hold mounting screws securely. There was a little wiggle and rattle between the mount and speaker so I had to figure something else out. And once screw is put in, Do Not Remove It! It will never fit snug again.

Pros: Great fit and extremely convenient.

Cons: Screws mount to plastic slots and which are not very durable or secure.

Very handy for mounting that eliminates the need to modify the door panel.

Pros: Easy install

Cons: Cheaply made. The way the screws tighten to the plate allows for the plastic to be malformed and prevent the mounting from being completely tightened. Can't add any type of mounting nut or lockdown with the design for my 6 1/2" speakers.

Work as stated. Used these to install some 6.5" speakers in my 2007 Silverado (new body style). They are a little flimsy, but the price is right. As long as you are easy with everything, shouldn't be any issues. We will see how they hold up over time. I did put some foam on the backside of these too, just to make sure they didn't rattle against the door.

I had to replace two door speakers in a 2008 Silverado. I bought the speakers from Crutchfield and these mounts came with them. They were simple to install and only took one mounting screw to securely mount it in the original location. They work great.

Nice fit to door but had to do some drilling so the speaker would secure properly isn't an exact match to the speaker but it's universal so oh well.

Pros: Fit perfect in the door.

Cons: Could use some sort of cushioning where plastic meets door for added reduction in vibration.

Written By BWade, Lafayette, LA on Tuesday, August 26, 2014

Crutchfield Customer Review (What's this?)

Used in 2007 Avalanche. Got these to mount some aftermarket speakers in the doors and they worked like a charm. They do require a little drilling and they do not come with any extra screws for mounting but other than that, they do exactly what they are supposed to and fit in the stock areas perfectly with no interference with the door panels at all.

Pros: Make it very easy to install upgraded speakers without interfering with stock appearance.

Cons: Require a small amount of drilling and do not include any mounting screws.

Written By Nicholas, Kansas on Sunday, August 10, 2014

Crutchfield Customer Review (What's this?)

These fit the back door well. They do not bring the speaker as far forward as the OEM. They do not make the wire adaptor for this truck yet. I cut the plug off the OEM speaker and soldered to the new speakers. I also cut the foam spacer off the OEM and glued onto the new speaker to fill the gap. The install went well enough. I will say I do not really notice a difference since the front stage over powers the rear stage. I would not spend the money again. on the back doors I would rather invest it in the front stage.

Pros: They fit.

Cons: none.

Does maie it easy to install speakers

Written By HumpMan, Charlottesville, VA on Sunday, July 13, 2014

Does make installation of replacement speakers in the doors of GMC/Chevy pickups very easy. Not quite as solid as the OEM speakers, but decent. Do wish they came with mounting hardware for the speakers (I wound up getting some nuts and bolts) and foam tape to go between the plate and the door metal would be nice. I did what others have done and reused the foam from the OEM speakers.

Pros: Makes installation dirt simple. Moves speaker away from door to move it closer to the door grills

Cons: Could be thicker or stiffer plastic. Would have been nice to have some hardware and foam tape included.

They Work, But Not Strong Enough

Written By sirbOOm, Atlanta, GA on Tuesday, June 17, 2014

Crutchfield Customer Review (What's this?)

Unfortunately, while these do work in the sense that they hole speakers in a goofy door cutout, they are not made of strong enough material for (1) heavier midbass/midrages, (2) I've seen speakers come out of these many times because the screw points are thin, weak plastic, and (3) to ensure the most midbass. You want a stiff, stiff, stiff, hard, hard, hard, dense, dense, dense baffle. If you can bend the baffle with your hands, then it's just not going to cut it, IMO. These are essentially only good for router templates, IMO.

Pros: Good for a router template

Cons: Not strong enough plastic. Should be harder, thicker, and not bendable.

Written By BV_Wing, NW Arkansas on Monday, May 19, 2014

They fit ok and made for an easier transition to the new speakers since the factory originals were pretty much glued to the same kind of bracket. I used sound deadening material to replace the foam backing between bracket and metal. Sheet metal screw does concern me for the long haul and vibration with the plastic.

Pros: Ease of replacement speaker mate.

Cons: Questionable screw attachment to plastic.

2013 Silverado Speaker Adapter

Written By BobD, Huntsville, AL on Monday, May 05, 2014

Crutchfield Customer Review (What's this?)

I used these adapters with Infinity PR6502is front speakers to replace the factory in my 2013 Silverado LT. Crutchfield included a wiring harness adapter that worked after a little tweek with some needle-nose pliers. The adapters fit the factory mount very well, however, the speakers mount to the "plastic" adapter with the sheet metal screws that came with the speakers. I understand that the adapters were free with my speaker purchase but I felt a little uncomfortable mounting my speakers to these plastic adapters with the speaker screws. They screw into the plastic that is slotted for the speaker hole mount. Will see how they handle bumps and bounces over time - for now they are snug. They were fairly easy to install. Recommend.

Pros: Easy to install and good fit.

Cons: Mounting hardware for the speaker itself is a little squirrely. I would have rather had small machine screws with nuts.

These do the job

Written By 2011 GMC Sierra, Northwest Arkansas on Friday, May 02, 2014

Crutchfield Customer Review (What's this?)

They function as they should. But they are pretty cheap and flimsy. If you have 6-3/4" speakers you have to break the tabs off (which is not super easy). Should just make a 6-3/4" bracket. I would highly advise getting some sort of gasket (or similar) material to apply to the edges that touch the metal parts of the door. This would help the speaker/sound/potential rattles.

Pros: Free with order.

Cons: bare minimum. needs foam or gasket type material at edges that touch the door surfaces. must break off inside tabs if using 6-3/4" speaker. kind of a pain! (but hey they were free)

This is the easiest way to install speakers on a 2006-13 Impala. Just install your new speaker to the adapter, then screw it in after you take out the factory speaker. No drilling, cutting, or headaches necessary. I have repeatedly used Scosche products because they have never let me down, and are made in the US.

Pros: Easy Installation, Perfect Fit

Worked fine, but my 6 3/4 RF speakers were a little too large to fit. Had to cut off some of the interior mounting tabs to get them to work. MINOR inconvenience.

Scosche SAGMHR-634 Speaker Mounting Brackets

Written By Volfan, Tennessee on Friday, January 17, 2014

Crutchfield Customer Review (What's this?)

Scosche SAGMHR-634 Speaker Mounting Brackets fit and worked great. I did have to trim all of the plastic tabs protruding outward to work on my Pontiac G6. I think you are supposed to be able to break them off but I used my band saw instead to cut them off. Being a sort of 'universal' fit adapter bracket for various model GM cars, it did take me a little time to figure out the best way to mount my speakers to the brackets to suit me ... but they did work really well when it was all done. Using Alpine SPS -610C Speakers I used their mounting adapter spacers between the speakers and the Scosche adapter brackets. Then I used some medium density foam weather stripping around the perimeter of the speakers to cushion and seal between the speakers and the door panels. My object was to make sure that the finished installation distance from the door metal to the outside edge of the foam was the same as the original factory installation so the door panel would fit good against the speakers. This can be accomplished by measuring the distance from the Scosche mounting bracket surface where it mounts to the door metal to the outward edge of the mounted speaker (and/or foam) ... then compare the same to the original factory speaker setup. Probably sounds worse than it really is but I'm just trying to help those of you that might, otherwise, have trouble. To sum it up ... I am very happy with this product and the end result ... they worked great!

Pros: A very good product that works very well to overcome GM's shortcomings ... of not leaving you any other options for installing aftermarket speakers.

Cons: The biggest Con is General Motors ... making SORRY proprietary speakers and mounts that will inevitably leave you without any other options to install aftermarket speakers. As far as this product is concerned, there are no cons really but they are 'universal' to some extent to fit various GM models and they might require a little ingenuity, innovative thinking and patience to figure out the best installation procedure possible on your vehicle.
