    cigarette lighter help

    Ok, so what i figured to be the easiest part of the whole thing.. as usual.. is not.

    I'm using a 150 W OPUS and I just plan on running power to it from the cigarette lighter.. so I cut the end off an old radar detector adaptor and soldered some wires onto the leads... but didn't get a voltage reading from them.. i got the right voltages when i put the leads directly in to the cigarette lighter (of course), but no voltage off the leads of the adaptor.. and ideas?

    NO NO NO NO NO NO NO!!!!!
    put everything back the way it was....
    Your cigarette adapter will not supply enough power to your opus, that is Why in the instructions, that you should have recieved in PDF format says to hook it up directly to the battery. You now may have to check your fuses in your fuse box. Shame on you, do not do that again!!! (I'm a teacher...can you tell?)
    then attach the red wire from the opus to the battery
    then the black wire from the opus to the battery
    the yellow wire is the wire that gets attached to 12 volt source (either found under your dash (ACC wire) or you can also find a 12 volt source in your fuse box...you can buy little fuse box a adapters that you crimp one end of you wire to, and then shove it in the fuse box just like a fuse to get that 12 volt. All the opus is doing is using that 12 volt yellow wire to know when to turn all the juice on. So as soon as it detects the 12 volts in the yellow wire, it turns the power on the power supply and powers your motherboard. It needs to have continuos 12 volt power to stay on...if it does not...it will turn off!

    follow steps below!

    Get it?

    GO to your local auto shop and pick up a 12 volt probe. After you get that you want to find a wire that will light up that 12 volt probe in your crank position of your keys as well as your on position of your key.

    man...don't make it any more difficult than it already is!

    If it stresses you out that much, maybe technical support isn't your forte?

    hm.. so when i posted a while back (months and months ago).. people seemed to think it was OK.. the only problem they really talked about was the regulation, but the opus seemed to be fine over the ranges the cigarette lighter put out.. so i guess thats not the case?

    so you're saying i have to get +12 and ground wires from somewhere under the dash, and can use the fuse box for the accessory wire?

    can i use the fuse box for all the wires?

    Is your cigarette lighter switched? or is it on all the time?

    It should be ran directly to the battery, I have man running off god knows what in my car. I spliced into some wires after probing and called it a day(i know, i know... shame on me).

    Every thing runs fine but my opus 90w doesn't survive a crank. So alas i must drill through the firewall and run it correctly.

    Cheers

    YOu NEED to run the MAIN power off of the battery...RED POSSITIVE, BLACK NEGATIVE. the yellow wire is the wire that needs to hook up to a 12 volt source either under the dash, or fuse box.


    This is one reason "Antimatters" is not working correctly, because he is not getting his power directly from the battery.


    Antimatter- you should beable to find some rummer gromets that you could poke some holes through rather than drilling...at least that's what I did.

    ok, yellow wire, got it -- ignition... dash. done.

    now with regards to the 12v/ground wires from the battery. im assumign you dont mean i should pop the hood, tie wires to the battery leads, run them into the car, and hook them up to the opus.. so where do i splice into the battery? (dash, fuse box, some where else?)



    to sort of guide your explanation.. i can read schematics, etc. i just dont know jack about cars.

    ok, so i've just about given up on trying to do this myself, gonna get it done tomorrow at a local stereo shop..

    just so i know what im getting done, if someone could just verify this for me, one last time.

    the three wires i need are
    +12 (from battery)
    ground (from battery)

    and IGN -- not ACC, right?
