  • 2011 MazdaSpeed 3 setup I am planning.

    The current setup I plan on useing is mainly based on an old computer I had sitting around gathering dust.

    Chip:P4 515 (p) 2.93 G 533 MHz Socket 775
    MoBo: Asus PTGD1-LA
    Ram:1G of DDR
    HD: 160G Sata
    PSU: DSATX 220 Watt
    Monitor: Lilliput 669GL-70NP/C/T
    Amp: TDA7850 Internal 4 x 50W Quad Bridge Power Amplifier


    I plan on running the PC for Audio, GPS, backup camera (later on), and for OBD software that displays guages and datalogs. I have a pretty large area behind my dash to work with for the MoBo and to add fans for cooling if I need more than what came with the computer.

    Any tips or suggestions are appreciated.

    1 - Behind the dash it tough. There's less room in there than you might initially think, especially when you consider the number of cables, motherboard mounting and so on. Make sure you have a backup plan.

    2 - Your PCU has a max draw of 84w. That's a 7A draw on the 12v rail. Using a DSATX, that leaves 5A on the 12v rail for anything else (motherboard, HDD, monitor, etc). It's something to consider in your build.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

      As for room there is plenty. The 2nd gen speed 3 has a cubby hole behind the glove box from factory. I took out that box and it gave me an 11x12x5 space to work with. Plus when I remove the factory head unit it will give me more room there. From what I could find the DSATX seemed to be the best option considering heat. Would I be better off with an inverter instead to give me more power? Later down the road I might consider upgrading to a different setup, but this computer is more than capable to do what I need.
