    Where do I connect a red power wire to the battery?
    Community Answer
    Community Answer
    Connect it to the positive battery post. That is the one with the plus sign. Red is positive; black is negative.

    What does the remote wire consist of?
    Community Answer
    Community Answer
    The remote wire needs a 12v signal to turn on the amp. Connect it to a source of power that is on only when you turn your key.

    Measure it according to the inches of your subwoofers and subtract 2 inches before cutting your box.

    If you do not have RCA ports, you'll need to wire in a line converter that taps into the rear speakers of the car.
