I'm impressed every time I see this build! He needed a Custom Subwoofer Box Plan for his 2022 Ford F250 Crew Cab to fit his 6 Ampere Audio AA-2.5 RVE 6.5" Subwoofers. Tim did an amazing job taking these Custom DIY Ford Crew Cab Subwoofer Box Plans we made for him and brining them to reality. He used a 2.5" Seat Lift to make this fit. The Stack Fab corners give it a nice OEM looking fit. Here is what Tim had to say for himself in this Review.

I had Justin design a one off custom under seat truck box for 6 - 6 1/2” Ampere Audio DVC subwoofers to go in my 2022 F250 6.7L Diesel. I already knew airspace and size were going to be tricky to get the 3 cubic feet to give each sub the 1/2 CF needed. I did utilize a custom 2.5” seat lift to help. The main thing I wanted was to not stick out really far from the front edge of the seat for comfort when people would ride in the back. I am a pretty picky person when it comes to my audio builds and asked for several must haves. I wanted flat stack radius corners, dual ports, and the subs recessed in the face of the double baffle. Lastly I wanted it to be able for the enclosure to be able to be stained do, which meant everything had to be super precise with every aspect of the design. Well….Justin did all that and more!! The design turned out to have everything I wanted and more. I build all my builds myself from sound deadening, wiring, enclosure fabrication and all the custom fabrication it takes to do a quality build that makes people ask how much did the shop charge you for that? My favorite answer is….SHOP? Nah man built not bought!! With all that said, Justin did a great job and the build turned out great. Whenever I decide to do another build Justin and Custom Lowz will be my first call. Lastly, everything with a custom audio build is designed around the space left once you have the enclosure. I didn’t have to sacrifice anything I wanted to do and it all turned out great!!! Thanks again Justin!!"

This box has 2.50 Cubic Feet Net after all displacement. Tuned to 33.71hz. You can purchase 2017-2025 Ford F250/350 Super Crew XLT 6 Ampere Audio AA-2.5 RVE 6.5 DIY Subwoofer Box Plans and build this box yourself! This would also fit the 2009-2025 Ford F150 Crew Cab when using a 2.5" Seat Lift.
