    I need help on powering everything (lilliput, wire size, etc) and audio hookups

    Hi people,

    I'm planing my install and looking for some advice on my power setup and on connecting everything together.

    since there are multiple inputs & outputs on both headunits, i'm a little confused, but thing i'v figured it out, except how best to add an ipod to the setup.

    The computer has no regulated 12v out for the lilliput monitor, but since it is a headunit would it have its own regulator?

    I'm not sure about the wire gauge or fuses at all, any help here would be welcome.

    Would it be better to feed the 12v acc for the amp from the headunit remote turn on line coming out of the headunit? will this prevent amp thump?

    Here is the power diagram:


    And here is the audio connection diagram:


    Thanks in advance, if you need anymore info on my setup, please let me know.

    You can connect your Lilli to your psu. Cut the end off one of your molex drive plugs. There will be red, yellow, and black wires. The yellow is 12v, black is ground, red is 5v. Double check with a multimeter.

    Not sure about the thump.

    You can run the acc from your headunit if you would like and that would solve the problem, however PSU like the Opus and M2 or M4atx have a remote turn on wire for the amp. Depending on your PSU i would just take it from there.

    Using the amp turn on from the PSU can sometimes cause your speakers to pop when the PSU turns on the amp that powers them. You could still try using the psu, if it pops then just switch it over to the ignition or the HU, it all depends on what works for you.

    +1 to powering your monitor from the PSU, you just use the yellow wire from one of the 4pin molex connectors.
    If you don't have an available molex connector, you can buy a Y cable that will split it into two connectors(usually come with video cards that need an extra power connection) . You want to let the PSU regulate the power. The fluctuating voltage can cause you monitor's backlight to go prematurely.

    Thanks for the feedback,

    I want to be able to run my headunit and amp while the pc is off, so via the headunit is the best option, reading the users manual it says its a soft power up for amps so all's good there.

    I've not opened up the pc, it came assembled, i will soon though and see if there is a spare molex connector.

    This is the 12v regulator i'm using for the bullet cameras.
    Spec: input - DC2V/32V
    output - DC10v/12V1.5A

    If i cut off the 2.1mm DC plug will it provide a positive and negative wire like on the input side? And then use that as regulated power.

    Update:

    I've opened the pc up and i do have a spare molex connector.

    The PSU is a M2-ATX-HV 140w

    Can i use cut both the 5v & 12v lines from the 1 connector to power 2 different things at the same time(12v monitor & 5v Usb hub)?

    You can use both the 12v and 5v line at the same time. Just check the wires with a multimeter like I said before. I have never seen anything other the yellow-12v, red-5v, but you never now.

    It's actually 160w.

    Yes.
    Yellow = 12v
    Red = 5v
    Black = ground
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    Ground it to the chassis.
    Rule of Thumb: Your grounds should be as short as possible.
