View Full Version : Car PC install in my B5 S4 Avant..

10-15-2006, 10:51 PM
OK, first off, this is my first CARPC, my first install, my first most everything..

2nd the car had a double Din Bose Radio in it.. I removed all the bose speakers and replaced them with Infiniti seperates in the front, 6.5" in the back doors.. They are run off the stock Bose amp (for now) with a stock 6" woofer..
I also have 2 @ 8" headrest LCD's for the back seats..

I have all these pictures in 8MP if anyone actually wants to see something better....
Ok, here we go..


OK, first off..wiring.. No kit exists, no wiring harness, nothing.. I used an Audi A6 Kit which is close to the S4 dash but not close enough to work without some work..
This was a cluster you know what.. I have a unit called a EFU that gives me my V1 Radar detector and boost readings on the computer between the tach and speed gauges, it runs off the stock radio plug and has lots of wires.. Then I have a Panasonic CD, Expander, Bluetooth, and Sirius Module and wiring.. Then all the wiring for the flip screen.. etc..
I know, it looks like my dash threw up..
As you can see, I am going to try to fit the Mac Mini in the glovebox.. I ordered a P1900 Power Supply from MP3Car but it is on back order, so for now, I have a normal invertor..


So, while atacking all this, I thought I would get around to installing my V1 Radar detector.. They are illegal in Virginia so I mounted it on the passanger sunvisor.. I had to extend the screws about 1 inch so it would fit right..
So, all wired up and working.. I put the XR1 Router with Verizon card behind the seat for now and connected to it through the wireless router. I connected the audio out from the Mac Mini with a PHONO to rca adapter to the Panasonic radio through the AUX input..
Ok, I know this is the most awful reskin EVER!!! but I just colored in the MITSU logo and copied a S4 logo over it.. I will get around to making my own when I have time to learn how..
So, I have to wiggle some wires around to get the 2 units to slide into the dash a little more, I also have to file down the install kit
I still have to figure out how to get video to the 8" LCD Headrest monitors..
Mac Mini is DVI out, I have a DVI to VGA Adapter.. I am guessing I am going to need to split that vga to 2 vga's, then get a VGA to RCA Adapter, then split that RCA to 2 RCA's for each screen.. I will attack that tomorrow..

Almost 1 AM now... Will send some more tomorrow...

Wow. Nice, I've seen it done in B6's but haven't seen a writeup in a b5. Looks great-

just so you know Metra now makes a dash kit for the B5 S4 and also has had a wiring harness out for a while now to make everything plug and play.

Metra harness: 70-1787 (VW/Audi Amplified Harness)
Metra Antenna adapter: 40-VW53 (amplified antenna adapter)

Dash kit:

nice job..where did you get S4 skin? you side it was a reskin but what did you start with? I would like to possabibly tackle this once I get my MBP

10-16-2006, 01:38 PM
I just took the normal skin which had a Mitsubisi logo on it and put a S4 logo over it.. It is a normal PNG file which you can edit in anything, I used Paint Shop Pro

I did have to buy an amplified antenna adapter, I got it from the local sound shop..

That dash kit says 2000 to 2001 A4 only..!!!
$75 is a lot of money for something that does not even say it will work........
I paid $15 for the A6 kit which I can make work..
If I did get the install wire kit, I would have even less room behind the radio... I did not even have to kit up the factory harness.. I cut up the piggy back EFU harness so the factory harness is untouched..

Metra has a new kit for the Symphony II double DIN head unit in the S4.

Metra 99-9105

AudioOutfitter.com and Installer.com also sell it. It is a perfect fit for the B5 S4 dash. I know because I bought one.

10-16-2006, 04:12 PM
Cool work
Do you have a picture of the dash from a little further back, so I can see the big picture?

very nice.. and confusing

but the most confusing part is that you have a mac mini with windows...

10-17-2006, 09:58 AM
Im curious on what is needed just to hook up the carputer and the flip out screen (wiring harness wise)

10-17-2006, 11:33 AM
flip screen just has power ground and switch, then a VGA cable and usb cable to the computer..

What did you do with the stock bose front speakers? I need one. What size are they?

10-17-2006, 10:20 PM
I pulled the front speakers out and they are sitting in my garage..
they are smaller than 5 1/4 because I put 5 1/4 in there and it was a PAIN...

So, 4 inch, maybe 4.5"... Whatever it is, it is what delongs in your car if you have the bose..

No idea what they are worth, I was hoping to sell the amp, radio and 6 speakers together..
What do you need??? all 4 front speakers or just one of them???

Going the same route here tomorrow. Have the same Lilliput deck and a VIA PC ready to go. I have the correct Metra dash kit for our cars coming as well. I do have one question. What wiring harness am I going to need to hook that Lilliput up to the Bose system since it has the amp and tuner built-in? I'm hoping the sound quality is decent through the Bose setup, if not I'll get a normal cd player later. Thanks [:D]

The new double din A4 kit is perfect for a double din radio, but if you are going to use 2 din radios it is too small, you have to really cut it up which is what I have now.

Make sure you get a Antenna adapter with a power line on it, it is for the VW's, any sound shop should have it.. I tried to find what harness to get but I could not find one and because I have the EFU unit I was not sure if it would work.. And I am/was pretty sure I was going to pull the bose amp out one day so I just piggie backed power ground and switched and cut the bose input connection...

there are 5 wires in the bose plug, the wiring is on the top of the radio.. you have to wire the 1 ground to all the grounds of the RCA cable and then hook the postives to the postives of the rca cable...

It was pretty easy, it took me hours of troubleshooting with no audio to figure out the amp cut on is in the antenna line, so make sure you get the correct antenna adapter and hook it to the switched or amp line on the radio..

I went with 2 seperate units because I wanted my daughter to be able to watch a dvd while I listened to Sirius or the radio.. And I already had the radio with Sirius and bluetooth... I think I might redo it all here shortly though to get rid of the Panasonic and use the pc all the time, I got a usb AM/FM TV tuner and you can get Sirius through the PC now.... After the Stage 3 install I will play with it.. Need to get some new pictures too, it is all installed now and working
