2019 Silverado box

I just received my box and it’s truly worth the wait. The box was packed up well to ensure safe delivery. The box fit perfectly and sounds remarkable. I love the terminals used as it allow for quick disconnection if needed. I also have the Jl Stealthbox and in my option this is far more superior

RE: GMC Denali Ultimate Custom Loaded Box

Master peace

No one can can understand that it’s just four little 6.5 I went above and beyond on the instal sound treatment is. Big big. I did my floor to I did a center channel with I amp you can. A they will make what you want …and there service top. Notch Don is the man. He see your vision !!!!!! For 12k and my labor you can not get a plug and play This impressive worthy of the wait. You just don’t comprehend the sound and then it breaks. I’m. And I might need some tweaks I’m it but I’m not calling cuz it could just be my old ears this is no joke you can here thing like your I’m a real sound studio recording in your truck. Plays every thing. So nice I’m still playing some music. Just for the sound experience Falco on that any ways get you some. And. Do a weekend. With your buddy. Installing it don’t half ass the sound treatment injoy. I am.

Made it too easy...

I've messed with car audio in a couple vehicles, but I'm no expert. I get the basics but these new bus'ed vehicles are beyond me. This made my sub upgrade too easy and was a no-brainer when i was deciding how to do my small upgrade. Beware tho, give a guy a better sub, and hes going to want better speakers to go with it! I'll be back with SGS before long.

Great Quality Product

These speaker adapters are of very sturdy high quality plastic that have been machined to a perfect fitment. The vacant speaker attachment holes are perfect for the installer to make a perfect fitment of speaker attachment holes. Pricey, but worth every penny compared to all the other brand options.

Absolute Best Products

Theses guys are the best !!!

Works exactly as needed

Very easy to use and simple to modify if you need to fit larger speakers. Worked very well for our application

Big Man Loyalty

4XL quality shirts. Zero complaints other than my St. Bernard's hair is very "attached" to the black shirts. Great design too

Perfect fit for Subaru Crosstrek

S.G.S is a gift for DIYers. Love them and customer service is on par with the product.
Thank YoU!!

Plug and play

Kit had everything needed to tie into my 2024 Denali 3500. Was really easy and even have the remote wire.

Great product

Great fit and very solid thick dense plastic very well made had to order the rears too.

The bass and clarity is insane

The process to properly sound treat the doors is a little mundane but the end result is worth the little work. The midrange and bass is more audible
