Has any one put subs in this specific body style? if so im guessing you put them behind the seat or is there a coller and kinda different way of mounting them?

my cousin's husband had 2 12s in boxes behind the seats and 2 6x9s in the corners. he just put them in truck boxes and he had corner boxes for the 6x9s

how does it sound?

I built a custom center console for a guy years ago. He had put buckets in the truck. Done many behind the seat boxes with 8's and 10's.
