    Problems in Wiring Amps

    Hello to every one!

    I bought two RockWood Detanator VII and already Connect the Black Wire to Ground, the red wire to 12V from the Battery and I have a yellow one that I don't know how to wire it. I am using a suplementary battery for use when I switch off the car!, So the question is... Can I wire the yellow one to 12V too?

    Thanks!

    Most likely that wire is a remote wire. that one should go to some switched power source, usually the blue/white wire out of any after market deck. or you could route it directly to the battery if you really wanted with a switch inline, but if you forget to turn off the switch you risk draining the battery.

    Hi there, i have a question along these sort of lines. I am building a car computer based on a laptop. I have bought a Creative Labs USB Sound Blaster Live! 24bit External sound card and am going to run the amplifiers from my sound system off it.

    The problem is that this obviously dos not have a remote wire from my amps. Can i just connect this remote connection to an ignition switched 12v supply from my car? Would this then mean that the amps come on when my ignition is on?

    I always assumed that this remote wire also controls volume too. But presumable this is actually controled by the 3v pre amp inputs.

    Last question, will the outputs from my external surround sound be at the correct operating voltage for inputs to my amps?

    Thank you - Tim

    Another question along the same lines. If you remove the old head unit in your car (to be replaced by a LCD) is there a remote wire in the factory harness that can be tapped in to for both the amp and the carPC?

    By your posted comment, if there is a blue/white wire out of the factory head unti there should also be a blue/white in the wiring harness, correct? If so, tapping in to this would give me the remote wire, correct?

    yes... just look up somewhere online the wires coming out of the harness and find the switched 12v wire and tap that

    run a 16gauge wire from the acc to the amp remote, that way you can still fire up the amps while the car is off.

    Be careful of your wire colors. Industry Standard is:

    Yellow: 12v Battery (High Power)
    Red: 12v remote input (Turn on Signal - Low Power)
    Black: Ground

    @Timmy C
    Yes, you can connect your amp turn on wire to the accessory wire of your car. Yes, this will cause the amplifier to come on as soon as you turn the key and will probably cause a 'pop' when you turn on your laptop. You may want to look into a more clever solution so the amps come on after the laptop (delay circuit, relay, etc).

    @Splash-X
    Yes, there is an accessory wire available at the radio connection. The color will vary from car to car, but using a harness adapter with industry standard colors it will be the red wire. You can test to be sure. This wire will go to 12 volts only when the key is on. This wire is low power (signal only).

    Out of a head unit the remote output wire will usually be blue or blue/white. This is generally used to turn on an amp or put up a power antenna as soon as the radio is turned on. This wire is low-power (signal only).

    Hope this helps
