    hi,
    I want my car stereo can power when the engine start, not when the panel lights turned-on.

    in short I want the car stereo power when there is an engine acceleration.

    with that wiring I can also top other wires for example my dc electric fan.

    what are your ideas? suggestions?

    get a manual for your car and look in the back for the cars wiring schematic is a good place to start

    hi,

    So, there is really a way to make this direct top connection, rather buying a delay relay(1 min) from an electronics store.

    thanks.

    yes you can properly take a 12volt feed from the ignition
    depending on current on that circuit if it can supply enough power

    possibly it wont epecily if you want to run other stuff off it

    another option is make another fused circuit and have to turned on via a relay that is supplied by the 12v ignition

    but im wondering why you want to do this as the there normally wired like they are so you got the convenience of not having to run engine when you want stereo on

    this may help you a bit



    if you can read a read schematic look in the back of the haynes manual BUT I WARN YOU THERE A PAIN IN ASS SINCE THEY STOPPED DOING EM IN COLOR LOL

    just don't nick a live from somewhere with a small fuse that will pop a small fuse time you turn up stereo

    if you got a massive head unit and amps seriously into you bass

    use a separate power circuit direct from battery and then engage it via a relay from a ignition live
