Question about Alpine Car Audio & Video
Connect the yellow wire directly to the battery (this is constant 12v power, to maintain memory settings). Red wire gets wired to the switched 12v system (so that the stereo turns on and off with the ignition). Blue wire (or blue/white) would be for an antenna or an amplifier (if not used, just seal it off with electrical tape). Orange wire isn't used (that's a dimmer wire for tapping into a car's dash light dimming). Black is ground. The rest of the colored pairs (gray, gray/black, green, green/black, white, white/black, purple, purple/black) are the speaker outputs. The wires with the black stripes are the negative wires in each pair. They usually say on them which color corresponds to which speaker location (front left, rear right, etc). If not, take a look on the Alpine unit - sometimes there's a decal or diagram on there, or a list, which will tell you which wires to connect to which speakers.
