I just fininished testing the wiring harness i made for my in dash computer so i thought i would show you guys because i have not seen anyone make one like this before.

My goal for my carputer was to use the stock HK sound system (i'm not much of an audiofile) and to fit the entire computer in the dash behind the lcd (yes i have managed to make it fit)

Next i am going to make an aluminum face plate.

If you guys are interested in how i am doing this let me know and i"ll post in more detail.




here are links to the products i am connecting to:

That looks great. How are you going to fit a PC back there? Even the mac mini clones out there (like the Aopen miniPC) seem too big to fit. Also, is there enough airflow for cooling the CPU? Post pics as you proceed. I'd love to see them.

I have seen many installs with the whole computer attached to the screen behind the dash...it is basically a double din carputer case where the front is a 7 inch touch screen that sits in a bezel like Rich's. You would have to do vent modifications for this, but i would imagine it not to be much different from any other double din install.

Sorry for my ignorance--- so, what you did was splice the respective connectors to the wiring harness? Any more info? Thanks. :)

No vent modifications, i'm using one of these:
http://www.mp3car.com/store/product_info.php?cPath=30_54&products_id=113

Its mounted upside down to the top of the plastic carrier for the oem headunit i have a video card that hangs down behind the screen, the power supply fits in under the mother board (barely) and the HD goes on top of the motherboard under the vents. Since the motherboard and video card don't draw alot of power they dont get verry hot and neither does the power supply.

I'll post some pics tonight when i get home from work.

I'm extremely interested in this. Last thing I care to do is rip out seats and carpet to run wires to the trunk - please post :))

since people are interested I'll post a written explanation now, and when i get home i'll take some more pictures and make a diagram with all the pin numbers.

First the audio, i split the audio wires from the harness into 3 groups: right+, left+, and all the - and connected it to a standard 1/8" stereo plug. I was told i would need a SEVEN4 device to do this but it was not necessary, I just plugged it in connected the wire to make the amp turn on and it worked perfect.

For the power i matched the ground, constant 12v, and switched 12v to the harness that came with the Opus power supply. The power supply also has its own switched 12v lead that turns on when the computer is on, I attached this lead to the power for the screen and to the wire from the harness that turns on the stock amp. (I think its labeled the antenna wire, ill check when I get home)

For the ibus I used one of those cdrom audio cables and just moved the white pin, it fits directly onto the ibus to serial interface I got. I also moved the dimmer pin in the harness to where the ibus pin should be (the harness comes with the ibus pin empty)

Actualy i guess there is not alot i need to add, just that the ibus is pin seven and the wire from the harness to turn on the amp is labled "power antena" and is pin 16.

without the sven and the way you have the audio hooked up wou will not have the correct Left front Left Rear Right Front and Right rear surround sound. You will be getting the same sound from every speaker the way you are doing it. I used the stock HK system when I did mine but I used the sven....with my new USB sound card i now have Dolby 5.1 surround sound....you should redo the audio wireing to make it better..the rest looks great! Still dont get how you are going to fit the computer back there but kudos!

Well it's stereo the way i have it. The front and rear speakers on each side are the same but the left and right are different channels, and my sound card is stereo so thats all i need.

Here are some pics of how i am mounting the computer, i realize it's kind of ghetto but it works. Also i still need to make a tray on the top to put the HD. After the computer is in the dash the HD will slide in on top of it through the hole for the air vents.

Looks Good! If I decide to go back to a CarPC this is definately the way I will have it set up. Less routing of wires and easier removal is definately a plus.

I'm assuming you will be using a FM transmitter thru the Carputer

Anyways best of Luck and definately post more pictures :thumbup:

this looks really promising...

i would stuff the gpa antenna inside if u still got room, rather than dangle it as u need it and plug into ur custom usb port....well i always assume that the GPS is a pretty important part of a carputer, but if u dont want it then i guess not

another question, so then how are u going about the radio? are u going to have a radio or just mp3

please post pics as u put the Xenarc in and all

thanks!

Really nice project man!

I am building a carputer too in my e46 M3. I did one in my old Prelude and it was great, replaced the factory deck with it... one issue though -- computers ALWAYS have problems and it wasn't long until I got sick of fixing it after it ran great for a few months then encountered some glitch... so I would wind up driving around with no tunes!

So this time I am building it into my H/K system... see this post to where I am mounting my LCD (it really is gonna work out nice I think). Here's the link: http://forum.e46fanatics.com/showthread.php?t=354192

QUESTION... What are the wires you tapped into at the back of the radio for constant +12V power? I need to do this to power my xenarc screen. Is there another place I can grab +12V constant easier than taking the radio out?
