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"

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.

Nice fit and very helpful with the 6 1/2" diameter speakers. All holes lined up perfectly, and the hardware and brackets are made of quality.
Cons:
This bracket could be improved if a foam strip was added around its perimeter to help resist vibration/noise; like the factory speaker brackets have.

speaker bracket

Written By BV_Wing, NW Arkansas on Monday, May 19, 2014
Crutchfield Customer Review (What's this?)
 
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.

Written By Dan s., Daytona Beach,FL on Tuesday, May 06, 2014
Crutchfield Customer Review (What's this?)
 
Brackets worked but screws supplied were to long, also mounted screws in slots in brackets after cutting them in half without clips(no room anyway i think).Tech support said to do this.I just hope down the road they don't strip out but so far working fine.Stock speaker bracket had foam backing which replacement bracket did not. So far everything works fine but will see in the long term. Installed in 2007 Silverado ext.cab new body style.
Pros:
Did the job
Cons:
Missed foam backing,screws supplied had to be cut and mounted in slots. I hope they don't strip out later.

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.

Easy Installation, Perfect Fit

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.

Written By GaryW, Saint John, NB on Monday, December 02, 2013
Crutchfield Customer Review (What's this?)
 
These were a perfect fit for the front doors of my 2013 Silverado. The smaller doors on the extended cab didn't accept them. This was brought to my attention by the Crutchfield rep who sent them anyway to see if I could make due. The truth of the matter was to take the OEM square bracket, hacksaw around the original speaker and simply install the new units with a bit of silicon and the supplied screws.....perfect!

Great for the full size doors

Don't fit the smaller extended cab doors

They fit good. Should come with some extra screws. Make sure when you install you have extra screws on hand to keep them from rattling.
Pros:
Make install easy.
Cons:
Needs more screws to hold it tight.

what other option is there?

Written By Rory, NC on Monday, October 28, 2013

I have an 08 chevy, the 6 1/2" fit fine. the 6 3/4" worked ok, just not as easy as lining up holes and screwing. I used the slot things they have. It got a LITTLE agrevating but not too bad. I was still able to use the metal tennerman clips the screws tighten in as well, just did one screw at a time and didnt tighten any of them untilI had them all started. My only thing is the factory speaker bracket is a "SCOSCHE" bit deeper (pun intended). Meaning it kind of put the speaker more closely against the door panel. I decided not to worry because maybe the aftermarket woofer could move more, and they space them out a little so you dont get a buzz from the woofer hitting the door panel. So I definetely would use again because, I really dont know what else I could do other than make a bracket....
Pros:
beats fabricating my own
Cons:
Maybe they could do something else for the 6 3/4" mounting screws? But it still did work...

The price was right and will do the job just fine

Written By AlD, Poughkeepsie, NY on Friday, September 27, 2013
Crutchfield Customer Review (What's this?)
 
The factory speakers had an integral bracket shaped like the Scoche brackets, so I needed these to retro-fit the new Alpines in my truck. They worked fine, but the holes that hold the speaker screws were rather flimsy and should have been a solid piece of plastic with a hole, rather than the slot that ran the full length of the support
Pros:
Price ($0)
Cons:
Not sure the speaker securing screws (4) have enough bite into the bracket.

Pros:
Good solid mount once I figuered out how the speaker mounted to it.
Cons:
the 4 long screws it comes with go through the speaker holes into the mount holes loosley and then bottom out against the vehicle door before it tightens up. I used my own srews with nuts and washers for a solid mount.

They fit the car door very well. Could provide a better way of mounting the speaker to the adapter,--very cheap, but they serve the purpose.
Pros:

Crutchfield Customer Review (What's this?)
 
I installed four of these units in my 2007 Chevy Silverado Crew Cab. These are for the new body style. If I would have not installed them myself and had taken the door panels off, I would have thought they were factory. I installed all four after mounting the speakers first in less then an hour. Units did not come with mounting hardware for the speakers so I had to use my own hardware.
Pros:
Perfect fit.
Cons:
No mounting hardware for speakers. That's why I gave it a four star rating.

Factory Speaker Upgrade

Written By Steve, Mount Pleasant, WI on Sunday, August 18, 2013
Crutchfield Customer Review (What's this?)
 
These adapters made the speaker upgrade simple. I replaced both front speakers in my 2500 HD pickup in 45 minutes.
Pros:
Matched factory interface perfectly.
Cons:
I would prefer that the speakers connection would have been a hole that I could screw the fastener in directly. There were 4 slots that required putting a nut on the back, which is inconvenient and difficult because there is little space.

Can't give five stars but - they did the job with a little trim. Installed 6.75 in. speakers - the little tabs on the inside of the ring were preventing a flush fit. A couple of minutes with a dremel and that was solved. After that - went in without any issues, problems or hassles. 2011 Silverado Reg cab door.

Have to trim inner tabs for 6.75 inch speakers to fit flush

Great product. Just take out the one mounting bolt on the old one. Mount the new speaker and re-install. Don't know why they don't have one for the rear speakers but I just took a jigsaw and cut our the old speaker and re-mounted the new speaker in its place. Worked just like the front bracket. I highly recommend these for a quick and easy installation.

Crutchfield Customer Review (What's this?)
 
Recently wanted to swap out the factory speakers in my 2009 Chevrolet Silverado Extended Cab and found that GM has made that task much more painful than it needs to be. I bought these thinking they were for the rear doors just to find that they're for the front doors, and pretty much nobody makes a bracket for the rear doors. Got these in the mail and tried them out, they kind of fit, could lock into the bottom a little better. I also had to drill my own hole in the top above the factory screw hole to bolt it into the door. The plastic could be stronger, to keep it from vibrating I put a little padding between the door and the bracket on each side. So far works pretty well, and for the price I can't complain too much.
Pros:
Price.
Cons:
Needs some tweaking to fit the rear doors in the 2009 Silverado Extended Cab. Plastic could be stronger.

I have a 2008 Chevy Silverado, and in 4 years my front speakers are blown, Dealer wants $40 each, and I could very well have the original crap. Another nation wide store with in house installation said they don't need the bracket to install the speakers! No, I didn't want them sheet metal screwing my speakers into my door panels. This bracket fit great, and utilizes factory GM mounting points, and holds a variety of speakers very securely. Be patient and order from Crutchfield.

Tough to use, depending on speaker

Written By Shank, Spring Grove on Sunday, August 26, 2012
Crutchfield Customer Review (What's this?)
 
Good product, would have been a solid mount if I could have used it. Lines up with the original gm speaker perfectly, does not accomodate all speakers securely though.
Pros:
Replaces stock speaker and mount to the T. Making for the best bass and sound distribution.
Cons:
Does not securely hold the polk audio speakers that it came as installation hardware for. The screws holding the speakers to the mount would have had to been wedged in a small plastic mouth designed to hold speakers in place. It did not seem safe or sturdy to me. However polk sends their own universal hardware that may be smaller, but worked 10x better.

Scosche SAGMHR-634 Speaker Mounting Brackets

Written By LPSTP, Scottsdale, AZ on Thursday, August 09, 2012
Crutchfield Customer Review (What's this?)
 
Requires trimming, so it isn't a "direct fit". I had to use some small wire snips to trim all of the tabs off of the inside ring (the speaker wouldn't seat into it otherwise). Then I had to use a steak knife (a razor blade would have been too light duty) to clean up the remaining burrs. I also had to use the clips that came with the speakers as a "washer" on the back of the mounting holes, otherwise I was screwing into flimsy plastic and Im quite certain that the speakers would have come loose in a short amount of time.

Not a task for everyone, so beware...

But after the required modifications it seems to be the ticket.
Pros:
Works

Requires significant modification

They work

Crutchfield Customer Review (What's this?)
 
The brackets fit securely inside the door panels. However I've found that the hardware included with the speakers does not provide a secure fit to the brackets as far as I'm concerned. Screws into the plastic bracket and cannot be tightened enough. I'm sure they will come loose and I will have to find another way to secure them to the bracket.
