in the dash are either a single 4x10 if you got the basic radio or dual 3.5's in each corner of the dash for the deluxe.no speakers in the kick panels, but you can get molds that hold 5.25 components. the rear are 4x10 in the cargo area. All the stock speakers suck. dont upgrade with the same sizes. you can switch the rears out for 6x9's with a little effort. if you want anything close to decent sound in the front, dont bother with anything in the dash,i made the mistake of doing that and it was a big waste of money. either get the Qforms kick panels with components or cut holes in the doorpanels for 6.5's. i would go for the kick panels, better sound and you dont have to cut up the doors. thats the plan for my truck.
