1993 Lincoln Town Car Underway (Lots of Pix)
First off let me say that this forum is soooo f’in awesome. I have always been very into car audio and upgrading cars in anyway possible. About 3 years back a friend of mine sent me a link to a car that had a computer installed in it (Thinking back it was probably a link to this site). Ever since then the idea of having a carputer had always lingered in the back of my head. The only reason I never took action on the idea was because I was so content with my car audio set up at the time in my 93 Lincoln Town Car. Well that all changed at the beginning of this summer when my little brother decided to borrow my car and smash it into the back of an SUV. The accident totaled my car, but all my audio equipment was ok. I was bummed for about a day until I saw an almost identical 1993 Lincoln Town Car on the side of the road for 2000 buckaroos (It is so identical to my old one, it really freaked me out). Well I bought it, got it all in shape and inspected, and then almost reinstalled my sound system. Luckily I decided to wait until I knew exactly what I wanted to do with the car this time. I had a fresh start and wanted to take advantage of it. I then proceeded to find this amazing site and from there I was determined to install a pc in my car. I feel bad because I am currently pretty far into my install but have just now started a worklog. I have just been really busy. I will try to keep this up to date with pictures and other information.
Below is a Parts List of all the parts I currently have….

As of this point in the install I have completed the following.
Integrated power supply with CPU
Bench Tested proposed setup
Installed Monitor into dash
Ran Cables and wires from front of car to back of car
Created Large Custom Fiberglass Box for Subs
Created Custom Amp Rack
Wired up and tested audio
Pretty much all that I have left to do is to create a sort of bracket to secure my computer to the car frame, Create a durable case for the computer, and then hook up the computer and proceed to fix the million mistakes I made.
I am trying to create a case out of ¾ inch mdf board. I am doing this because I am installing the computer in the trunk with the subs and I want to do everything I can to protect it from the harsh vibrations of the subwoofers. Right now I am running a standard desktop hard drive but if it fails due to vibration I will probably just upgrade to a laptop drive or spend the cash on a SSD. I know this forum is filled with information on how to protect drives from vibration (those off roadin dudes), but if anyone has any personal suggestions I would love to hear em.
I am at work now, but when I get home I will proceed to upload pictures.
Problems Problems and more Problems
Alright. Like I said I have more pictures to post of the install (Dash, Wire running, Computer Harness) but I just havent gotten around to posting them. I will try to get on that soon. Ok so yesterday I had the system up and fully running and I ran into some problems that made me go insane.
At first start up everything was fine. Computer booted up nice. I heard the boot up sound come from all 4 speakers and subwoofers. BUT my lilliput screen was not working. The light power button led was flashing redish orange in a pulsing manner with no picture. I was running the power for the screen back from the computer's yellow 12 volt and black ground line. I wanted to make sure the lilliput was still operating correctly so I spliced into the power and ground wires right after the 12 volt regulator and hooked it straight up to the battery. I am pretty sure I accidentally mixed up the polarities becauese the 12 volt regulator sparked and blew. At this point I am furious but of course I dont give up because I dont let stupid carputers ****** me around. I go inside and get out my regular ac adapter, grab a small power inverter and hook it up to the cigerette lighter, and it works! such a releif. I am not sure what was wrong with my innitial hook up and I dont know what that flashing light means but I am just goign to try again today and check everything 5 times with a volt meter.
OK so I have a picture. Next problem touch screen wont operate. Well I bring out my laptop and hook it up in the back (screen and usb) and the touchscreen works fine. So then I knew the problem lied within the computer. I simply reinstalled the touchkit driver and then everything was a go.
At this point I start having some fun and playing music and navigating through centrafuse. Satisfied with the days work (well nights work it was 3 in the morning) I decide to go inside. I turn off the ignition and notice the computer just cuts off. No minute delay like the m2-atx is supposed to. Also sometimes the m2-atx would actually re-boot even when the key is in the off position. Well I was confused for about 10 minutes and then out of no where it hit me like a ton of bricks and I wanted to kill myself for this mistake. I remembered reading a long time ago in this forum somewhere that you cannot hook the m2-atx up to the head unit ignition because that ignition is killed then restarted as the car cranks to not damage the head unit. So reallly when I turn my key I am starting the computer, killing it, then starting it again. This explains the hard off then the reboot. So that was my stupid fault and I am going to fix it today by running it directly to the ignition line next to the key.
Anyways those were my problems last night. But the future is looking promising.
Also at one point I got a white screen with vertical rainbow lines. It was only quick and went away but def. has me worried. To my knowledge that has something to do with the ribbon cable. Is tha right?
Does anyone know what that flashing redish orange light means on the screen?
fixes, and new problems. woo hoo
Alright i did some tweaking today. I realized that it is not smart to install at night when you cant tell a red 5 volt wire from a yellow 12 volt wire. Yea, I originally hooked my monitor up to the 5 volt ant that explains the blinking orangish red light that I had going on. I hooked it up to the yellow 12 volt line and everything was ok. While I had the dash all apart I also took apart the lilliput and made sure the ribbon cable was not being interfered with. The biggest thing that I accomplished today was successfully hooking up the remote wire for the m2-atx directly up to the ignition and not the stupid head unit lead. There is minor feed back (faint static sound) but I feel this can be fixed with better grounding. You see I ran a 4 gauge ground straight back from my battery and that was not smart. 4 gauge is far too small, and the wire is far too long to properly ground the cpu, monitor, high amp, and low amp.
I think that I can correct this by finding a nice grounding spot in the trunk and running a thick 2 gauge wire to it. Also, i have yet to do the BIG 3 up front.
QUESTION: When I turn my up, with the bass level at a moderate to high level all the sound in my speakers cut out and i only hear the subwoofers. It literally sounds like it just sucks the juice from everything when the subs hit.
Is this due to grounding you think? Do you think by doing what I mentioned above (ground and BIG 3) I could fix this issue? it would be ideal if it was because that would eliminate me needing to upgrade the alternator or get a new battery.
