aiyo...dismantling and fixing up different leh. Do you think the
mechs will need to think which wire connect to which part? Or which
pipe connects. When dismantling to parts, a mech dun really need to
care whether it is connected or not. They will do that only when
they are installing or fixing up which requires the mech to be
carefull, as a malfunction could lead to battery explode or damage
the car wiring system.
Sound system will take time especially those which are harder to
install type. They got to make sure all the wirings are done up
properly. you expect them to do a snappy job and in the end theres
no sound???
Just take a jig saw puzzle for example....do u tink fixing it up or
dismantling is faster?
