single 12 sub box?

[MAka]

Im looking for 2 single boxes that fit 12s so I can place them in my plastic bi behind my seat in my reg cab. My cousin has 2 in his night runner but he get them from an audio shop in fl and im in ny. Anyone know of any? Ive seen these huge boxes and custom boxes but I want 1 12 behind each seat and then I want to have my storage bin in the middle.
