The Subwoofer Boxes I Tested
The [Bbox A372 12CH Dual Vented Subwoofer Enclosure](https://www.amazon.com/s?k=Bbox+A372+12CH+Dual+Vented+Subwoofer+Enclosure&tag=thetestedhub-20) was the hardest hitting. Dual ports and a tight under seat fit made it the favorite for daily driving.

Common questions
Ported gives more low end output and feels more impactful for hip hop and rock. Sealed is tighter for jazz and classic rock. Most Silverado owners I know go ported.
Shallow mount 10 inch subwoofers fit best. Some 12 inch shallow mount boxes work but you lose more rear floor clearance.
