anyone that cuts the lower section of an RA40 dash should have there balls tied to a length of rope attached to a brick and then the brick thrown out the window of a moving car.
not only does it fuck the whole dash frame it its way way waaaaayyyyyyyyy out of your line of sight when driven'
Anyway radio up there some 4inch ones in the doors, 6inch splits in the rear arm rest trim or replace back seat with a storage box/6x9's and a small sub if thats your thing...
