manufactoring process car stereo

Not quite sure what you want to know.
In terms of car design, the fascia can be designed around fairly standard dimensions and then some relatively off the shelf electronics can be bolted on the back. I'd guess these things have a standard footprint/fixing points etc. Go to your local car hi fi place and have a look.

If you want to know how the electronics are built....
Same as any other electronics. surface mount components picked and placed and soldered by robots. Someone somewhere designs the circuitry...but they are probably all based on the same chipsets and subassemblies these days. The sub-assys are clipped/screwed together by robots or cheap labour.

Maybe you should ask a more specific question?

thanks for the reply

to be more specific... the materials used?

stages of production?

You are having a laugh!

Go to the scrap yard, take an old stero out of a car.
Dissmantle it, whilst examining the aeshtetics and mechanics of the design and trying to see how it was assembled (stages of production)...
you will learn far more from the experience than you will ever gain sitting in front of a computer.

The materials used????
What do you think?
Steel, plastic, glass fibre or resin impregnated paper for the circuit board, copper wire, solder.
You'll be asking me what the electrolytic capacitors in the power supply are made of next..... oh, that'd be an aluminium can with some stuff inside.

Del-

You're giving this student excellent advice, but I bet he or she won't take it. For one thing, I suspect he's at a "design" school rather than an engineering school and doesn't own the needed tools to disassemble a complex electromechanical device not intended to be serviced.

The manufacturing process for a car stereo isn't just one process. The multiple porcesses involved can go all the way back to mining sand (for the silicon to make the ICs) and bauxite (to make the aluminum for the housing) and petroleum drilling (plastics from which the fascia is molded).

I have the tools for dismantling complex electromechanical devices...

A crossbow will dis-able a stereo, computer or other such complex device. Clearly the VCR in the picture has been rendered inoperable.

But dis-assembly so as to learn something about the original assembly process is a whole different kettle of fish. For that, you need to pull or pry snap-fit parts apart gently, unscrew threaded fasteners, deploy snap ring pliers and bearing or gear pullers, etc. I used to teach automotive engineers how to do this with our own and competitors' products in order to do materials and tooling cost analysis.

Then there's tearing down a product that's been through durability testing, where if you introduce scratches or dents, it contaminates the data from that unit.

You are quite right of course.
The tear down of competitors kit is always fun, it sounds like you have a fun job.
For dis-assembly I use the drop it from a great height method.
I did actually strip down that old DVD player out of curiosity.
It irritates me when snap fit 'arms' are not designed with any taper, and insead of flexing smoothly they all too easily snap off at the root. (That's just the naturall irritation of a bowyer I suppose)
