What kinda of system
 

I just got a 1995 Toyota 4runner 4wd and it doesn't have a CD player so Im looking to upgrade that but my question is what size speakers are in the Dash and in the Rear and do you know were I can find a how to on doing custom speaker installs like in the doors or in the kick panels? Thanks Ryan

the ones in the dash are 4inch

forget the dash... they point to the ground.

make some baffles and mount them to the doors...
