Here is a really nice build Robert with Midwest Intense Audio in Wichita, Kansas completed for his customers 2024 GMC Sierra Denali Crew cab. Using out plan he not only got a great looking box, but a box that performed well also. Using (2) Audio Dynamic 3008 8s. We incorporated some plexiglass side windows to show off the woofers, Rounded Corners to match the seats curve, and front firing aero ports! Check out the awesome with Robert did on this project. If your in their area. Id suggest checking out Midwest Intense Audio. Robert said "BY far the hardest underseat truck box I've built. But came out nice and definitely sounded great! Moved some serious air!

You can try these plans out for yourself. HERE
