    Sorry to be hogging your thread but are you simply looking for a turn-on wire or to power your computer. This is fine as a turn-one wire but NOT TO POWER your CarPC.

    Take a look at the FAQ: How to Wire an OPUS PSU to help you out if you're looking to power the CarPC. Basically, you will need to get the power if directly from the battery. I do not recommend using the cigerette lighter plugs for this even if you are using an inverter. Go direct to the battery but use the information that I posted above to turn the power on and off.

    yea, no im not going to power it from there lol. i will run a line from the battery. i just figured it would be easyer to get the ign wire from the radio harness which will work, i just got to get out there one day with a multimeter.

That's the portion of the diagram that I think would help the most.

    EDIT: Looking at the double-din Monsoon sub thread someone says the gray wire will work. This wire does not react with the ignition but instead is hot when the stereo is on.

    EDIT2: Per the12volt.com wiring diagram for a 2000 Jetta:
    Code:
    2000 Volkswagen Jetta Stereo Information
    ----------------------------------------
    Constant 12V+	Red/White 
    Switched 12V+ 	Gray/Blue 
    Ground    	Brown 
    Illumination 	n/a 
    Dimmer  	n/a 
    Antenna 	Left Front 
    Front Speakers 	6 1/2" Doors
    Left Front (+) 	Blue/Black 
    Left Front (-) 	Orange/Blue 
    Right Front (+) Red/White 
    Right Front (-) Orange/White 
    Rear Speakers 	6 1/2" Rear Doors
    Left Rear (+) 	Red/Light Green 
    Left Rear (-) 	Orange/Black 
    Right Rear (+) 	Blue/Light Green 
    Right Rear (-) 	Orange/Red
    Looking at this, I'd say Gray/White is what you're looking for. (PS. I am not familiar with Jetta years so hopefully the 2000 and your 2002 are similiar.)

    great thanks, i will probelly need those specs when hooking up the stock speakers to the carputer, amp and subbox.

    Unfortunately that little wire is not going to be able to pass the current needed to power your CarPC. The cable that is/will be going to the amp(s) for the sub(s) will work. I'm running with a 4-ga cable. Take a look the the12volt.com's Recommended Power and Ground Cable Sizes to get an idea of what size cable to run. Take the RMS of your amps and power supply and get the appropriate length of your car. Don't forget the cable is going to be running up and down stuff that will ultimately add to your length. Split the line at the end with a fused power distribution block to send the power to your amp(s) and PSU. That ignition wire will come in handy when it comes time to wire everything up becuase that wire is what will turn on the amp(s) and PSU. Just be aware that in some installs the stereo system will POP when the sound card is initialized. Search the forum for POP AMP to get some ideas to remedy the problem (I recommend a delayed relay timer.)

    I interpret that as saying he will not power the whole PC from the signal wire for the radio. He says he's going to run the main power from a separate line from the battery.

    nooo. im NOT going to power the psu from the radio 12v line, that is dangurus and hell. im going to run a 4 gauge wire from battery to a distro block. then a 8 and 10 gauge wire from the distro block the the amp and psu. im only going to tap into the switched 12v line which is in my radio harness. this would make the most sence because the radio harness has the leads i need for the speakers so i can connect them to the amp and not cut into any factory wiring.

    EDIT: He's not looking to power the system through the IGN like I inially assumed. He's simply looking for an easy way to have remote turn on for the PSU & amps. This is in reponse to EsKaLad's question:

    The thing is that (I thought) his initial goal was to run the system off this wire/connection. Same thing would apply if he went to the fuse box. That line simply cannot push the amount of power to (safely) run a PSU. It is not a thick enough gauge wire. He'd run the risk of a fire trying to run a moderate amount of power through a (probably) 16 or 18-ga wire. To supply he needs a line going straight to the battery with a wire atleast 12-ga in size (perferably 10-/8-ga for just the PSU; thicker for PSU & amps). Either tapping behind the stereo or at the fused can be used as a remote tigger (turn car on, equipment turns on).

    no dude i am going to run a 4 gauge line from the battery, i need a ign line, so i will use the switch 12v radio line (that is the line that turns your radio on when you start your car)

    i will use this connect and i will have leads for every thing and not cut and factory wire

    I know where you're going with it. I made a typo in the last post (corrected). I think at the beginning I was under the impression that you were wondering if you could simply run power through the IGN wire. You're on the right track with running the 4-ga for power and using the IGN wire for remote turn on.
