    opus powersupply question (newb)

    what wires do you need to run to the opus for it to function porprly

    im planing around a putting my system in the trunk and i have a 12v plug there however i notice that the opus has three input wires
    ( i think i read one of them is to sense the ignetion of the engiine or something liek that so it can shut the carputer off and on witha delay )


    anyone want to fill me in.


    and overall is a opus powersupply worth the money / functionalyt as aposed to just useing a inverter and a regular powersupply?

    Sorry but i have to chuckle at 'rugular'...i promise i'll make it up to you with helpful information.

    The three leads that go to the opus are red, black, and yellow. You should connect the black one to chassis ground (so any bolt in your car that is well grounded...anything into the frame should work), connect the red one straight to the battery, and connect the yellow one to something that has 12V only when the car is on. Is the 12V power supply in the trunk switched? If not, you should find one that is and use that to connect your yellow wire to.

    by switched i mean something that only has power when the car is on...there has to be SOMETHING in your car that meets those requirements...some light or feature or outlet that you can tap a wire into....

    Yes, it only triggers the Opus on/off so it takes very little current (< 50 ma). I tapped mine from one of the wires from the radio harness. The main current is supplied from the Red wire which you normally connect to the battery (with a fuse of course).

    then take the wire to the fusebox if you have one inside the car, find a fuse that goes live when you switch the ignition on and tap it to that on the fused side
