  • 2005 chevrolet cobalt install

    Hello, I've been reading on the forums for some time now and have been purchasing components for my carpc build and will soon be ready to install. I'm hoping I'll be able to get help in this thread as questions arise.



    I've already purchased...



    PC

    Intel D945 with atom processor

    1 gig ram

    m2 power supply

    Radio

    Directed HD radio

    Monitor

    Touchscreen liliput EBY701 (waiting for delivery)



    Need to purchase

    4 channel amp (undecided on model)

    power distribution block

    Wiring

    Probablly a bunch of other stuff





    My first question is about the IGN wire.

    The pc, hdradio, monitor, and the amp will all need an IGN source.

    I know there is an available spot in my fusebox to add this(for the optional sunroof), but is it safe to run ALL these devices to the same fuse?

    I got the infinity ref475a on ebay for super cheap its 4 x 75 watt RMS and harmonaudio is running the auctions every few hours. My winning bid was $45 but came out to $56 after tax and shipping...its a little scratched up and I havent tested it but I feel good. I'll be installing in a 2002 cavalier so I probably have the same questions as you...lets see who else chimes in.

      I wouldn't.
      Your safest option is to run a power line back to the battery, especially considering the equipment you intend to use (PC, touchscreen, amp(s)).
      Have you looked in the FAQ yet?
      How about the Wiki?

        I plan on running a power line back to the battery. That would be my always hot line. I'm talking about the IGN wire. Will connecting all the IGN wires from my devices to the same IGN wire be safe?

        Thanks!

          For the IGN wire, yeah, probably.
          There's very little current, as it is just used for sensing voltage to trigger turn-on.

            Hey False - take a look in the worklogs - my co-worker (cmotors on here) just installed his into his 09 Cobalt. He covered everything pretty well in there in case someone else with a Cobalt decided to do an install.
            Actually - here's the link - http://www.mp3car.com/vbulletin/work...est-route.html

            The nice thing with this car(I believe it's the same on the earlier versions of it) - is that the battery is actually in the trunk/spare tire well.

            We tapped into the WindowRAP circuit - fuse 17 - so that you've got power for about 10 min after the car is off, unless the door is opened - that's when it'd send the power off signal to the PC.

              Thanks for the link Sargeants, that definately gave me a few ideas.

              I'm still trying to figure out what size wiring I'm going to need. Just for the computer I used this link http://www.thermaltake.outervision.com/Power to figure that the pc will draw about 74 watts. I'll call it 100 watts to be on the safe side.

              Now to figure the amps you do watts/volts.
              I'm confused how to get my volts. Would it just be 12 volts?

              100W/12V= 8 1/3 amps Right????

                rate your fuses based on the m2 power supply you're going to use. make sure that it can power your system/screen/accessories, or upgrade to a larger/better power supply.

                and yes, the 'average' from the car would be 12VDC

                  Rate the fuse based on the wiring you use, and size the wiring based on the power supply. Never put a larger fuse than you wires are rated for, no matter what you have hooked on the end of it. 12 gauge ought to do you fine for the kind of power you're looking at.

                    The m2 is 160 watts so thats plenty of power for everything I'm running.
                    I just wanted to make sure I was calculating everything correctly.

                    Does anyone know of a free program to easily illustrate my setup. To make a schematic of all the components and the wiring.

                    I was doing it in paint but figure theirs gotta be a better way.

                        So does this look correct for my power?

                            Your results may vary, but based on personal experience, as you are getting the m2-atx I would power the + and - for the monitor both solely off the 12v rail from the PC (yellow and black off a drive cable). I had the +12v from my monitor coming from the PC's 12v rail, but the monitors ground to chassis ground which created a ground loop which affected the general sound quality, and oddly kept the Directed HD from getting any reception.

                              I'll take mshowman's advice and ground the monitor to the pc's power supply also, thanks. I also now intend to connect the ACC line from the monitor, hd radio, and the amplifier to the pc's remote out line. Is there any danger in doing so?

                              I'm also not sure about my amplifiers power.
                              It's a 320 watt jl audio amp.

                              320watts/12volts=26.66amps.
                              Battery is in my trunk so I'll need 6 feet of wire at the most.
                              I should only need a 10 gauge wire to power my amp????
                              Is that gonna be safe? The manual calls for a 4 gauge wire.
