Hello Everyone,
Yes I am a newbie, iv been reading and reading all the posts I could find on settings up a car pc. I have made a diagram of what i want my setup to be like before I acutally buy all the parts and start getting down to the nitty gritty. I was wondering if any one out their could check out my lil picture and add comments on what its missing and what I should change or how you would do it. I appreciate all the help.

your setup looks correct. make sure to connect the amp on to the power supply to avoid the 'thump' when you turn your car on. And maybe just to clarify you only need to use the yellow and black line from the molex to feed the screen.

Witch power supply are you talking about.. The pc power supply? If so will it be able to pump out enough watts for that?

Sorry I wasn't clear. By your picture I'm assuming you're getting the 3688 from Logic Supply.

It says that the PSU is a M1-ITX. Well the M1 has an "anti-thump" option for amps. It just replicates the ACC for your amps. So instead of wiring the automatic turn on for your amps to the ACC, you wire it to the M1 so it controls when your amps turn on.

You still run dedicated power to your amps, the wiring to the M1 will just be there to avoid the "thump" on turn on.

* High efficiency, 90 watts output
* Works with 12V / 24V car batteries
* "Anti-Thump" Amplifier remote control

OHHH GOT YA.. Yea i was thinking about that carputer. What would you rate it as. Does it carry a good enough GFX card to pump out good frame rate with ROADRUNNER or even StreetDeck. Or is their other options around that price range that would be suitable also.

that unit you listed is bone stock. 256mb ram is pretty low. I went with 512 myself. And 800mhz and only a 90W psu. With the stuff you connected it would be just enough but no real room for expansion. Check out the various power calculators to see what I mean.

I've got a MII 10000 with 512 ram and I'm still having problems playing video. Road runner runs fine, no real resource needs there. Not sure about the requirements of Street deck.

What kind of issues are you having with the video, Are you trying to play dvds, divx or other type of avi or mpg media. 800mhz and 512mb of ram should be good for playing any type of media no real hard renders for a cpu. Could be the GFX card memory is very low. Thats what i was worried about with theise small systems it comes with everything you need but small things like the GFX card and the FSB is going to be low.

I've dl'd the various codec packs like FFDshow from afterdawn.com but I still have a ghosting and colour problem when plaing in windows media player. In VLC player the image is a lot better but the picture seems dim with a bit of artifacting. CPU usage sits at about 25% with RR and GPS running in the background.
