Custom Speaker Adapters - Compatible with 2014-2023 GMC Chevrolet Vehicles

Brackets seem well built. Was short on the mounting bolts and there was no block off plate. Maybe I misunderstood what was included.

I reached out to SGS about custom speaker adapters for some Audiofrog GS62s for the rear doors in my Silverado. They were able to make them and could not be happier with the quality of them! If you need adapters don't hesitate to but from SGS.

The speaker adapters that I bought for the 2018 GMC work out just fine the craft work of adapter was excellent. I will buy from them again.

I got the speaker adapters and the block off plates. Waiting for good weather to put it all together. After seeing how much material you get for soundproofing I did a little research online I found that the sound deadening material is probably meant to go behind the speaker inside the door (inside of outside door skin directly behind the speaker) This will help with sound being redirected off the door and blocking the low frequency response of the door speakers and rattling. Makes sense seeing as there is one sheet per speaker, definitely not enough to cover the whole outer door panel. Very nice product and if you get the complete kit it is a complete kit, all you need to make a huge difference in sound. I have no doubt that once installed by hypotheses will be proven correct.

Gap where the speaker meets the adapter

I loved the speaker adapters, they fit perfectly and are very high quality. My installer stated that he had never seen such high quality adapters. My only request would be to provide slightly longer bolts for the bottom 2 holes. After putting on the sound deadening material, that extra thickness made it a little bit of a challenge getting the washer and the nut on. But that is very minor.

Really good quality and attention to detail. Easy to install and fits perfect. If you’re looking to replace the stock 6x9 with high end components I recommend this product.

Ordered up front 6x9 brackets for my 2016 GMC Sierra 3500.
Install was complicated due to my speakers large magnet hitting the window track.
Don helped me out and sent me some spacers that bumped it out another inch.
Installed brackets and spacers.
Worked out well.
Due to the thickness of the original bracket there was some trimming to the inside of the door panel.
Very satisfied customer.
100 times better than the cheap Metra brackets.
Thanks!

Product is the Best made. Sturdy and durable very satisfied customer…

Just installed the front speaker kit in my 2016 Malibu, it worked out amazing. They fit great, came with all the hardware needed and was straight forward installation. I have tried many cheaper adapters and these sound the best by far. Highly recommend this!!
