im a friends s10/s15 ... not sure what it was , wut 4 6.5's in a center console, 2 firing up with a cup holer made of pvc pipe in the middle and 2 firing towards where your legs would be and it sounded readdy decent... nothing too special because the box was just made for a test fit and he didnt have enough money at the time for really good coax's, so he settled for 2 pair of jensens for 20 bucks lol... still sounded nice

i would get pictures if this was an idea for you if you have no center seat but he sold the truck already...
