2015 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

Used these brackets to mount JBL GT7-6 speakers to the rear doors of my 2015 Chevrolet Silverado Crew Cab. Holes in speakers and brackets did not line up. Had to drill holes though the speakers and the brackets. The construction of the bracket interfered with the back of the speaker and the speaker would not lay flat on the bracket. Obviously the manufacturer of the bracket cannot manufacture a bracket universal to all speakers without some sort of problem. Have an assortment of screws, nuts and bolts on hand.

Pros: Enabled mounting the speaker to the door.

Cons: Had to drill the speakers and the brackets. had to use different screws other than those provided. A pain to work with.

They do what they are made to, just a spacer ring, not enclosed at rear as picture suggests, require modifications to make speakers fit, suggest adding your own foam between door and plastic as well as between speaker and plastic. This eliminated all rattles in door on my install.

Pros: Useful to mount speaker in proper location

Cons: Require modifications to fit speakers No foam to reduce bass transfer to door

Written by: Rolando from edinburg, TX on January 31, 2016

Crutchfield Customer Review (What's this?)

Scosche speaker mounting brackets fit just right on my 2008 GMC Sierra. The only thigh is that you have to remove the tabs inside the brackets for tone 6-3/4 inch speakers to fit flush. No big deal just snip them off and your done. I did not use the slotted anchor points that are on the brackets because when I secured the speakers through them it did not feel solid enough, felt that with the vibration of the truck and time the speaker would come loose. I just drilled the mounting screws through a different hold on the speakers through the solid part of the mounting bracket plastic. That anchored the speaker better to the bracket, more solid. The brackets aligned perfect in the door and the speaker baffles gave it more secure snug fit. All in all they worked great on my doors and they were included with my purchase of the speakers. Thank you Crutchfield.

Pros: Great fit for replacement brackets

Cons: Needed some modifications, no big deal

Easily replaced the factory speaker bracket. The screws to hold the speaker wouldn't tighten up to my liking. I had to find some that were small enough to fit the speaker but large enough to tighten up. Having these allows you to save a little time by letting you have a complete assembly ready to go when you remove the factory speaker.

These were a must to install speakers in the front doors of a 2008 Chevy Silverado 1500. The stock openings are squarish, so just pulling the onld ones out and installing new speakers would REQUIRE some fab work. With these mounts, it was a breeze. It has tabs for installing a 5.5", or you can break the tabs out to install a 6.25" speaker. There were minimal instructions, but if you can't figure this one out... you have no business pulling your door panel off to begin with.

Pros: Great product. Fit perfectly. Works for both 5 and 6 inch speakers.

Cons: NONE

Crutchfield Customer Review (What's this?)

Got these for upgrading the rear door speakers in my 2015 Silverado Dbl Cab with Kicker 6.75. The back of the speaker frame is too big to allow the speakers to sit flush on the adapter. I had to take a pare of side cutters and remove the plastic speaker mounting holes that stick out towards the center of the adapter. My speakers didn't need these holes and once they were cut away the speaker dropped right in and sat flush with the adapter. The mounting holes didn't line up perfect but close enough. The speaker mounting screws supplied by Kicker were to narrow to bite into the adapter's plastic mounting hole. They get snug but not tight. The speaker still seemed secure and with the way it is mounted in the door I don;t thin it will be a problem but I will keep an eye on it. The adapter secured tightly to the door frame.

Pros: Allows an upgrade from factory speakers. Fits snug in speaker opening and door frame.

Cons: Had to remove plastic to allow the 6.75 Kicker to sit flush on the adapter. Kicker mounting hardware screws were too narrow to tightly secure the speaker to the adapter.

Very dissapointed I will now have to return these and modify the factory brackets in my 2011 silverado. I measured my speaker and it is exactly 6.5"...I thought for sure it would fall under the 6.5 to 6.75" specification of these brackets, boy was I wrong!

These are a very close match to the molded plastic surrounds on the existing speakers. I took off one star because A) they don't come with any usable instructions B) for my particular installation I had to remove some plastic tabs that were on the brackets (instructions would have made this clear) C) the tabs don't remove cleanly, (they need to be dressed afterwards) D)the screws dont really go in holes, they kind of thread in slots, which makes them fit various sized speakers, but I fear they will loosen with all the vibration. That being said, I had really no issues installing them, they did fit the speakers/vehicle & you can't really expect more since they were FREE!

Pros: fit perfectly in my vehicle

Cons: No Instructions

They are not quite as tall as the factory speakers they are designed to replace, I had to find some foam tape to fill in the gap above the speaker rim otherwise there will be a road noise from the space.. The factory design was about a 1/2" taller and they fit closer to the grille.

Pros: Similar to factory

Cons: No foam tape or screws included and they may require trimming.

Crutchfield Customer Review (What's this?)

I don't know why manufacturers love making it so we always have to buy adapters. I know they have to position the speakers just right to match their door panels but can't they design to use a standard speaker? The Scosche speaker brackets made it a breeze to swap out the proprietary factory speakers with aftermarket's. Once I removed the door panels, it took only 5 minutes to remove the old speaker and install the brackets. My only complaints are the brackets could be stiffer and they should include metal clips for the speaker screws instead of stripping the soft plastics

Pros: Easy install Time saving

Cons: Plastic is soft and easy to strip out the speaker screws

Long lasting and durable.

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.

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?

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

2014 Chevrolet Silverado 1500
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.

2013 Silverado Speaker Adapter

Written by: BobD from Huntsville, AL on May 5, 2014

2013 Chevrolet Silverado 1500
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

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

Cons: None

2008 Silverado WT,. used these adapters with Rockford Fosgate 6 3/4 speakers .. in packaging Crutchfield also included wiring harness adapters so that there is no need to cut up the factory wiring harness. These adapter enclosures worked perfectly. very easy to install with the provided instructions. Strongly Recommend.

Pros: Outstanding Fit and Function .. keeps stock location with no modifications needed. Strong Recommend

Cons: None
