Love the adapters but didn’t get both sets of speaker harnesses hopefully you have good customer service.

What a great product! Saved me time and MoNeY!

These speaker adapters saved me hours of router work and made the door speaker install go extremely smooth. Thank you for making such an awesome products. Now please make block off plates for the 2018 Yukon Denali ;-)

Highly recommend

You won’t find a better quality adapter out there, don’t cheap out on then cheaper options as you will pay the price later.

Great Package!

As all of the product I have purchased from these guys have been, these are of great quality and a perfect fit. My frogs are happy and sound awesome in their new home.

Speaker brackets

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

Heavy Duty Speaker Adapters

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.

Is excellent craft work

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.

Great set

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.

6.5 in speaker doesn't sit flush

Gap where the speaker meets the adapter

Our Mounting Cutout Diameter is: 5.6-inch / 142mm. Some speakers that are based off of home audio drivers (PA Style Speakers) are not a traditional size. If you need us to open up the adapter to fit your speaker, let us know and we would be glad to make it happen for you. Thanks

Absolutely perfect!

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.

‘17 Mustang GT 6.5” woofer brackets.

Sounds good stereo has now made all 3 sets of speaker brackets for the front 3 ways. Their quality is excellent and they include everything you need to install the speakers. They also turn them around real quick which is a bonus.

What a great product!!

2020 F150 Sounds Good Stereo Amp Rack is an awesome product and time saver. I am just starting to assemble my system and love it. So far have 1 Hertz Mille Monoblock and 2 Hertz Mille 4 channels, Helix DSP Pro MK2 not much room left but shouldn’t need much more. Will have Mille Legends 3 way active, 2 Hertz coaxial in rear doors and 2 Hertz MPS 250 shallow subs under seat hopefully a SGS sub box.I used SGS block off plates as well and they are great as well

Perfect fit & Great Quality

Finally finished the install. Used #8 7/16 self tapping screws, which didn’t penetrate through the amp rack. I have the highest recommendation using all the Soundgoodstereo products.

Harness works great on my 2018 Silverado.

This harness is nice. Just add a Line Output Converter to it if you have an amp that uses low level inputs.

I waited over 2 months from another company and only got a reply from them once I filed a PayPal claim. These guys had my order to me in a week.

This says it only works with 2019+ trucks, but I took a gamble on my 2018 since the pin out looked the same between them. Works great.

Awesome Box!!!

I couldn’t be more happier with this purchase. The box and craftsmanship is on point! Makes the whole truck feel different including the bass. Great job guys.

F150 amp rack

Perfect fit and excellent craftsmanship

Perfect for under seat amp rack 2021 Tundra

I ordered both passenger and driver side panels. Installed 2 Alpine PWE S8 powered subs, 4 channel amp, LOC and dist block

LOC and 1 powered sub on passenger rack.

2nd Powered sub/ 4 channel amp/ and distribution block on driver side.
I had seat jackers on both seats installed so all my equipment cleared well.

My Tundra was a SR work truck package, so no factory under seat amp. but there was existing mounting holes

Amp Rack for f150

The amp rack fit perfectly and is professionally crafted! Would recommend this product to every f150 owner!

2018 F150 harness

Great quality, and well made. Will definitely shop there again.

Great Product with Easy Plug & Play Setup

Easy Plug and Play Setup made with good quality.
