Here is a updated overview of my DIY high end audio system in my 2021 GMC Sierra AT4. This build has been about two years in the making and seen many, many different iterations. I can finally say that the build is actually complete and wanted to make a video walkthrough of the system to prove some further detail of what went into the build. This is also to serve as a reference for SVR 2023.

The walkthrough is little over 40 minutes long and there about 13 minutes of some key build log photos.

I’d say there are over 600-700 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!
