First thing you will need to do is to buy a wire adapter for your specific make & year of car. This interfaces the stock wiring plug allowing you to connect the wires from the headunit to the wires of the plug.
Here is a color coding explanation for the wires on your Alpine Deck:
P o w e r
Memory (+12v Constant)
Ignition (+12v Switched)
Pink/White (Alpine only)
Light Blue (Sony only)
S p e a k e r s
Right Front (+)
Right Front (-)
Left Front (+)
Left Front (-)
Right Rear (+)
Right Rear (-)
Left Rear (+)
Left Rear (-)
Here's the color codes for the wires.
Blue/white=remote turn on for amp
Grey=right front (+)
Grey/black=right front (-)
White=left front (+)
White/black=left front (-)
Violet=right rear (+)
Violet/black=right rear (-)
Green=left rear (+)
Green/black=left rear (-)
Red=right rear to amp
White=left rear to amp
And that should be all the wires. Good luck!

If the alpine 8020 is a deck(head unit) the wire diagram is as followed:
Red: Accessory Yellow: Constant Power Black: Ground Orange to orange/white is a illumination or dimmer wire. White: front left speakers Grey: front left (white black and so on usually the negative on the speaker connections) Purple rear left (purple black = neg) Green: Rear Right And if a video deck(light green is park brake) (which is usually just a ground) so legally it needs to be on your park brake but can be grounded to make it work.
Speakers? (Terminals larger one is positive, smaller one is negative) Place capacitors on if needed to filter out and clear up bass
Hope this helps couldn't look uo what a alpine 8020 was..
The radio either does not have the yellow power wire connected(constant 12v) or the wire is connected to a switched source and when the key is turned off the radio has no backup power. You will need to pull the radio out and verify the yellow wire is not connected to switched voltage and connected to constant power. It is also possible that they have the red and yellow wires mixed up. Remember yellow constant power and red is switched power(with ignition key). And also disconnect your negative battery cable when working on the electrical system of your vehicle...you may short something out and damage your vehicle's electrical system or head unit.

facing the back of the 7940 the top left corner is pin 16 the top right corner is pin 9. The bottom left is pin 8 and the bottom right is pin 1. Only a few of the 16 pins are used due to this unit only having pre-outs, no internal amplifier on this unit. Pin 1 red (ignition), Pin 2 pink/black (interrupt), Pin 3 orange (Illumination), Pin 8 black (ground), Pin 9 blue (power antenna), Pin 10 blue/white (remote turn on), Pin 16 yellow (battery).
So it is powering up? On your actual deck will be a picture of the schematics of the wiring. With the system powered up, assuming you taped up the power wires, strip the front left wires coming from the deck and use them as your tester. You now know forsure they are for the front left so as you go through your cars audio wires you will find which wires are for which speakers around your car. Label them as you test them. Hope that helps.
