    Help! How do you test a Pioneer HU before buying it? you test it through the battery right? I just want to see it light up and read a CD. There's 3 wires: RED, BLACK and YELLOW

    Do I combine the RED & YELLOW and tap it onto the Positive Battery terminal?
    Then the BLACK to the Negative terminal?

    Just want to make sure, don't want to blow it up

    Why not let the sales clerk (from where you're buying the unit) do the testing before buying the unit?

    Is it safe to combine the RED(12v Ignition) and the YELLOW(12v Constant)?

    If i connect just the yellow or just the red to the positive and the black to the negative, the unit does not light up.

    Any suggestions GuRU's?
