    Wiring Diagram. Need lot of advice.

    Hey all...
    Well.. after quit alot of reading.. i'm still confused.
    Figured it'd be better just moving ahead, and asking on the board as i'm going...
    I've made a fairly simple circuit diagram.. and have questions already on it.

    I don't know much about wiring these components, for example, the opus connections..
    If there's anything unclear, or something i need to add to this...
    PLEASE let me know..

    thanks!

    //edit: i've heard some ppl say that you shouldn't ground to the car battery, but instead to the car body.
    So i updated that on the diag..

    go on.. point out the flaws! :0

    1) Xenarc 700 series going to a Lilliput touchscreen? A screen going to another screen? What's that all about? You need a Lilliput or a Xenarc, but not both.

    2) The amp's rating should be based on the RMS rating of your speakers. You want the RMS output of the amp to be within the RMS rating of the speakers. For optimal perfomrance, you want the RMS rating of the amp to be as close to the upper limit of the RMS range of the speakers. For the four 50w speakers you specify, a 200w (50x4) would do nicely.

    3) Take out the switch between the batter & the Opus. The Opus has a startup/shutdown controllwer so you don't need a power switch (although you can still wire one up if you choose).

    4) There's an ATX power cable bundle that goes from the Opus PSU to the motherboard. IT looks just like the ATX cable in any other ATX power supply.

    It looks like a good starting point.
    Have you looked in the FAQ yet?
    How about the Wiki?

    get a distro block on the ground connection of the battery and connect all your ground cables from all your devices to that distro block.

    avoid having different grounding points, it could create "ground looping" and noise/whine in your speakers.

    use the grounding point of your battery.

    just my little pointer

    PS: good diagram

    lol.. sorry bout that.. i meant that i wanted to use this cable: http://www.mp3car.com/store/product_...2997cabba4842e

    the length is perfect.. but i can't imagine the pins being different on a lili/xenarc.
    then again..i've never seen any of these touchscreens! lol..

    so..would this cable work? if not, do i just need a long *** vga and usb cables?
    (i've forgotten why the RCA's are there...)

    distro block.. sounds like alot of ppl using it.. but isn't it just a "many to one" ground device? anything special bout it that i've missed?
    Can't i just bring all the cables to be grounded to a central point? is that the samme thing as using a distro block?

    The RCAs are for the additional video inputs (DVD player, reverse camera, gaming console, TV tuner, etc).
    I don't know if that cable will work w/ Lilliput brand monitors. I'd email someone fromt he store and ask before you purchase, just to be on the safe side. It might work.. It might not...

    It's basically the same thing, but it's a lot cleaner way of wiring it all together.
