2021 GMC Sierra AT4 - High End Audio System Overview - Accuton, Helix, Mosconi, Focal, Audiofrog

Here is a detailed overview of my DIY high end audio system in my 2021 GMC Sierra AT4. This build has been about 18 months in the making and seen many, many different iterations. I can finally say that the build is complete and wanted to make a video walkthrough of the system to prove some further detail of what went into the build.

The walkthrough is little over 22 minutes long and there about 13 minutes of some key build log photos.

I’d say there are over 500 hours into this build between all of the iterations but I’m extremely proud it.

Please leave any comments below and thank you for watching!
