It'll look like this but tan, I found this one on CL and the guy had installed a JL Audio single 10" in it. They come powered and non-powered, don't know what the OP has, but mine's non-powered. The interior color match is perfect, IMHO. MTX discontinued production (at least for the crew cab 05>)
I had a 2 x 10" one in a regular cab F150, they are overbuilt, very solid, thick boxes. The CC one replaces the passenger side tool tray and you secure it with the tool tray tabs.
On an unrelated subject, nice pic! My first born's name is Amelia, my family goes back to the 19th century there.
