I had been searching for an option that would give me more bass on my 2023 F-350 Lariat with B&O Unleashed. After reading the reviews, I pulled the trigger on ordering this sub enclosure with the Sound Treatment kit. I am beyond happy with the results. It is a perfect balance of bass for the B&O. These 6.5" subs are very impressive. Enclosure is engineered perfectly for behind the seat. I highly recommend getting the Sound Treatment package as well. The sound is more full, doesn't have the hollow effect without the treatment. And best of all, with my music cranked to the max that I listen to, NO RATTLES on the outside of truck. Had enough to do all 4 doors (inside and out), all 4 door panels, and the rear panel of the cab.
