Infotainment System for Porsche Car [from CAD, prototyping to finish]

This is awesome! A question regarding the cooling, though. Where is the air intake? And how do you make sure it's not blocked in any way?
Am I correct when I assume that since this unit will extend far less deep than a regular stereo unit, there will be a lot of cooler air behind it, which will be used for cooling?

A: Back panel, middle-left side. Is not an intake, its an opening. The fan act as exhaust.

A: I don't. You get to do this! Although not exactly sure what you mean by that

A; Doesn't need to be "cooling" specifically. I do advise on air circulation however. Refer to previous thermal model to know the air volume you'll need to equalize the temp in the unit.

Lastly, on the subject of 'cooling';

Auto makers already design their vehicles for console cooling, that is how they get away with dash electronics cooling in most of today’s vehicles – also to prevent ears from popping violently when opening the windows (neutral pressure eq). Mostly passive and relying on buoyancy (although not exactly sure how they manage the latest in a 'n' shaped dash, secret I guess). Your cabin/dash is not sealed water tight but you guys knew that already.

Because our kit is The-Best-in-the-World, ours absolutely NEEDS active cooling! Really depends what you do with it tough, if for listening music or for deco only (1~2watts CPU usage max) then passive cooling is sufficient. I’ve plugged in the active cooling for “Ultimate Performance” reason as I (personally) plan on beating the CPU in many ways (real-time OBD fast query and data logging, listening to police radios + FM radio simultaneously (with my newly acquired UV HF RTL-SDR tuner!!!), and/or while encoding H.264 media, etc etc… All At The Same Time if I need! You get the idea

But again; Intel chip… it comes with factory built-in protection e.g. start throttling at 80dC and auto shutdown at 90dC. Gives you an idea of what this little devil can withstand

WOW Fred. I'm trying to follow some of the tech talk and this is fascinating. BTW, the headunit was the first thing I replace a month after buying. Its only been about 10 months and already went through 3 headunits. BTW, Im not sure I saw this earlier but will there be tuning options like Xover points, subwoofer phase, gains front and rear...etc? I am running a Kenwood KMM 515 Mechless unit at the moment. I had an Alpine ute-52, but the Kenwoods speaker/sound tuning won me over.

Yea it got pretty high tech at some stage but I think we are done with this tough. The rest is mfg & play really. Already started the CAM work on the small parts and plan on manufacturing the IPS display frame and back enclosure as soon as I receive my pre-order on material.

RE Sound

At some stage in the built I’ve realized that none of us here have the same goal or/and taste for sound so I’ve simply enabled an AUDIO OUTPUT + MIC INPUT. You can obviously shoot this audio output straight in the Porsche OEM amplifier using a 3.5mm jack to RCA slitters (example) or (copy me) and go for a USB 6 Channel 5.1 HD external sound card. I kind of like the Creative Sound Blaster because of the software that comes with it but you can buy anything else that is plausible to you and within your budget e.g. 7.1 Surround Sound, subwoofer support and all! All very inexpensive stuff… search Amazon keyword “USB HD External Sound”.

That's right! Full Surround Sound in-a-car lolllll

I’ll provide the computer (same as a laptop really but 3x smaller). What you want to do with it is your choice! If you want to hook up a 1000W-RMS Alpine amp and 16 subwoofers to it, be my guess man

Lots and lots of Boom Boom options for you guys to choose. Obviously.

Be creative fellas
